The car's not modded except for a header and exhaust, and a cone filter. It should pass if everything works right. Passed last year (just barely...) and I haven't changed it since.

The county I am in for school does not have emissions testing.
The county my cars are registered does.
With out asking for any paper work, I was inspect in the emissions free county, just signed a paper saying that I would have emissions tested when I returned to my home county. Just had to sign a paper saying I was there for school.
You could always give that a shot...
When I lived in Houston I had to pay the guy an extra $100 bucks every year

Here's a clapped out 1986 non turbo with 550 injectors and a RTEK2.1 running only E85, plugs that have not been changed in yrs and gosh only knows what other lack of maintanence. Ancient cat from Catco vintage??? four yrs ago or more.
I worry not about emissions no 'mo a'tall. Zoom, zoom.
Actually the figures are not that much better than regular gasoline imho.

Wish my '79 hadn't popped it's seals, though I do like the way the FC drives and handles.
The '90 and my wife's '08 Kia are the only cars I have with emissions required, but they're also the only running cars I have out of 5.
Magnaflow cat came in yesterday. I need to have Ye Olde Muffler Shop and Cheese Emporium install it, and we'll see what happens.

I think in Tx, the 1986-87 cars only have a couple of more yrs and then I will not have to have the roller test anymore. After that I think they just look for things in place and the normal things like headlights working, brakes working.
Then again, that's why we have a state legislature. To write new laws to override the 25yr and older exemptions for older cars.
I was running on half tank E85 and half regular last yr with stock 460's on that car and the emissions were comparable to the yr before with plain regular. Had to use the RTEK 2.1 to run it like that though. Had to crank a lot of additional fuel using the 460's on that blend.
And while here...........if ones car suddenly accelerates and keeps accelerating.........am I the only one who would have enough sense to turn the key in and anti clockwise direction????? I'm beginning to think so. I sure as heck aint a gonna put the sucker in neutral or stand on the brakes and call home on my cellphone (woman's a idiot that did that on her Toyota runaway car).

On Morning Joe, MSNBC (an severly infected broadcast medium), they showed this morning what to do if the Prius goes in to auto acceleration mode. .....first put both feet on the brake pedal, then hold joystick (that's what they call it evidently, some call it the shifter who've never seen a Prius) to far left so it'll go into neutral. Then once into neutral steer off the highway. If it does not go into neutral, push the OFF button (takes three seconds before it responds to the push) and when the engine stops then guide the car to the side of the hwy.
One of the co-host Mika, says "you have to rememeber how to to ALL that????". Geeee whiz golly, there's no hope for this country says I.
I wonder. If I buy a Toyota, are the chances of the one I buy going into auto acceleration, better or worse than my buying a Lottery ticket and winning?
I'll stop now. I'm off topic which was???????????????? forgot already.

Well, crap.
$150 cat + another $40 for another test and it still fails. Everything's lower, but the HCs are still 300 on low speed.
I took it to test right after having the cat welded in, and the guy at Kwik Kar told me I should have run it in 100 miles or so. 'Course he tells me after it's tested...
So, what do you guys think? Anything else? Alcohol? Direct air from the air pump to the cat? Clean the ACV? Pull the engine and put it in my '79 chassis?
I'm searching the forums now...

A point of data I forgot to mention above: The O2% this time around was 0.0. It was fairly low on the previous tests: 0.2 and 0.3.
This says to me that maybe the ACV or the air pump is fubar or otherwise not getting enough air to the cat to burn off the excess HCs.
Time to break out the manual and actually diagnose everything rather than throwing money I don't have at it, I guess.
Well, at least I thought to grab the old cat and keep it, since it's likely good. I mainly grabbed it to get the 3-bolt flange that the muffler-monkey cut off my header with the cat. Didn't really want my exhaust to be one piece from the engine to the tips, but I didn't think to specify that flange should stay.

If you look at some of my past tests-failed or passing-you will see some excess O2 and a percentage of 'dilution'. When the test is failing, there is more excess O2 and when failing there is less excess O2.
You *could* hook your air-pump up directly to the cat just to pass the inspection.

HC is the only thing failing - it's at 300 PPM. Everything else is way below spec.
I have the test reports scanned and can post if it helps.

If not, the air pump gets connected straight to the cat for long enough to get to the station and tested.

FULLY HEAT UP THE ENGINE. Then pull the very large hose off the side of the ACV. Is there a very large amount of air coming out??? Rev the engine over ??? 3800 and see if the volume of air is much larger. You should get SOME air coming out that large nipple on the ACV, but that's just a bit bypassing. When the engine is rev'd the amount should be much larger as you get up to around 2000 and above.
If there is a large amount of air coming out at idle, then look at the ACV. Just above it should be two small vacuum lines. Not attached to the ACV itself but located just above the ACV. Idle the car HOT and pull 'em off one at a time. Each should have vacuum on the hose. If not, write back and we'll tell you what is wrong.
Your problem does seem to be the ACV not delivering air at low engine speed like it should, to the exhaust ports. Once the engine is driven over ?? 1500rpm or so, the ECU goes into closed loop and the afr's go to stoic. The ACV at this time may/may not be delivering air to the exhaust ports. Not really required if the ECU is in closed loop. That explains to me why you pass the 25mph test and not the lower speed 15mph test. Lack of air to the exhaust ports at low rpm.

Yup, that all matches up with the FSM, but a lot simpler to understand.
I wasn't clear earlier: it's not passing at either speed Th high speed is generally in the 200s, low speed in the 300s. This last test I think he had it in the wrong gear for the high speed - I could hear the engine lugging, and the RPM was 1443 rather than the near-2000 from the previous two tests, putting the HCs in the 300s there as well.
Not sure I'll get to the diagnosis today - the honey-do list is taking more time than I thought - but I'll get to it after work this week if need be.
I appreciate your help, all of you!

Actually got a chance to look at it yesterday.
Initially, I found that the air pump is working, and air flow increases with speed, but, all the air was being bypassed to the ACV exhaust, none to the spilt air.
Checking the two solenoids, I found that the Solenoid Valve (Relief) blue plug was partially disconnected - it was only hanging on one terminal. Plugged that back in and got air out of the split-air feed. volume seems to be low, but it is flowing, and it switches over at about 1500 RPM to the ACV bypass.
Check valve on the split air seems weak - there's a little back-flow when the hose is disconnected.
Just for grins, I tapped into the oxygen sensor and got 0.05-0.06V at idle, and 0.8-0.9 at steady throttle above about 1900 RPM (no load.) That means that it's way lean at idle (not so odd), and pretty rich at cruise, if I'm reading the charts on the net right. 0.45V should be stoichiometric.
The only spec in the FSM for O2 is 0.5-1.0V during accelerations and 0-0.4V on deceleration.

Sounds like plugging the RElief solenoid plug back on fixed the problem.
At steady speed over approx 1500 rpm, and actually DRIVING the car, the ECU goes into closed loop with the 02 sensor and the output will be stoic and you'll pass the higher speed test better and ..........with the ACV now sending air to the EXHAUST PORTS (not split air pipe, please) the low speed test should now pass.......hopefully.
At idle with a hot engine you can look at the 02 sensor output. Lean reading. Then while idling, pull the blue plug off the Relief solenoid and the 02 will now read the rich 0.80 or there abouts. Proves the ACV is functioning thru being controlled by the Relief solenoid and ECU input to the relief solenoid.
Air going to the split air pipe will have NO effect whatsoever on the 02 sensor .....ever. That air is injected aft of the 02 sensor. PORT air sent to the exhaust ports is located prior to the 02 sensor, therefore air going there WILL effect the reading of the 02 sensor.

Makes perfect sense, thanks.
I'll let the cat run in for 100 miles or so, then take 'er in and see what happens.
My TPS was also out of whack - I had to screw the adjustment back in (clockwise) quite a bit to get the one light to come on.
The only other tune-up item item left would be spark-lug wires. I'm not replacing those 'til I measure their resistance.

It just passed. Relief Solenoid Valve was the culprit. The cat that was on it may have been marginal, given last years numbers.
It blew 79 PPM HC on high speed, 100 PPM on low, well under the 168/173 spec, respectively. Only 0.1% O2 left, so it could probably do with a bit of leaning out, or more air from the air pump, but what the hey, it passes!
Thanks for the help and advice, guys!

So since you are trying to make political commentary, how bout this thought:
Out in your land of tree hugging, spotted-owl loving, tingle-running-up-the-inside-of-your-leg, crossdressing liberals, you get to pollute to your little heart's content. IOW, you get to pollute (this is too easy) 'Liberally'
And in Texas, we actually care about making our air clean by requiring our cars to run right. Maybe this is why the word 'Conserve' is the root of 'Conservative'.
Now, who has been watching too much MSNBC?
Just yankin' ya.

This isn't the lounge. You should try not to post to the tech forum when you are drunk and, uh, in your words looking to '****' someone. Please note that my status is currently 'In a Relationship' so you will need to '****' with someone else.
Further, you should attend to your spelling and grammar.
FYI, The slag to whom I was responding in that quote had his offending posts removed by the moderator. Might you be next?
And don't forget to vote!
Good Luck!

Rotary Freak
So, being in the Dallas area, I took my tests to Rotary Performance for advice. They advised that the cat was probably cooked and that any cat is only good for a couple of years on a rotary. Even the RP Bönez the HC's, it was obviously toast.
I passed with flying colors!
I passed with flying colors!
Here's something to get your attention: I run three RX7 on ethanol. Half the reason is the octane value and the other half is to pass emissions each yr with no heartburn/doubt.
Attached is my results for a 87 TurboII yesterday. Compared to your results mine are not as good. Go figure. Just in case..........I run on E85.
Mine is the first jpg attached.
