so i failed in two areas

one beinf the THC levels (which are supposed to be at 2.00) and i scored a 31.87
second area is in Co levals (which is supposed to be at 32.0) and i scored a 105.3

as you can see it pretty bad i have a stock nikki carb with a farley good street ported 12a and it has about 2200 on the portted motor from pinnaple that has about 12k on the whole thing. so yes emissions controls are gone and the chracole canister and so on. but i have a high flow cat with rb header and a straight through muffler with about 2 1/2 inch piping. so i need help i know a big thing is that i am going to turn my mixture level down and try to run leaner as i can smell that kinda gassy smell sometimes. but besides that i am at a lose please help.

 

I will be amazed if you will be able to get your setup emissions legal... You really should have looked into this before doing all that work.

And oh ya sell me the engine for cheap! lol

 

does the r/b cat have a pipe to hook up the air pump? if it does you can hook an air pump up real quick and run it straight to the cat. that helps alot. thats if you have the air pump and/ or can find one.

 

well i do have the air pump kooked up and it does go to that pipe that leads into the cat so wow i may be in real trouble. lol.

 

Kettlman, did you repaint your car? It looks. .. . . different somehow.

 

Without the nest or canister, you're pretty much screwed. I can sell you my nest for only a tiny bit more than shipping (all intact but the A/C part) if you need it.

 

well i have both and all the wiring is still there but it would be a bitch to put back on but is that my only option i mean come on people please help. did i also metion i have till the fith since i already got a ticket for it

 

yes, i did repaint and change hoods.

you got a ticket for the emisions? was it directer for the emisions or cause it wasn't done? and on your air pump. does it rout through the intake manifold like stock? or is it directly hooked up to the cat? another thing that just ran through my mind...... what if you ran nitrous straight to the exhaust in real little increments? that would throw some dense oxygen into the readings. that would be funny."well sir, last time you had a 31 and a 105.....now you have a .03 and a 6. what the hell did you do to it?"

 

Lol! A good use for nitrous! Good one Kettlman.

BTW, the car's looking sweet. Is the hood custom?

 

lol ya so when the guy is doing the pull on the dyno just tell him hey hit that switch a couple of times or she will die lol. but not the little hose from the intake is hooked into it and then to the cat. anyway the pump could be bad. i mean i wouldnt think it would through it off that much. but heres the thing from my understanding one is for fuel and one could be oil fumes so do i do a oil change and then, since my metering rod isnt on now, put oil into the tank to make it a little less potent??

 

well first off, i would hook the pump straight to the cat, bypass the intake with the pump. that helps in washington. as for your omp. if you disconect it you need to run pre- mix. use regular boat pre-mix. there are plenty of threads about that and what kind to use. or the mmo pre mix. just as many threads. you might wanna throw some high octane gas and fuel additive to help clean it up some too. and if you don't have a charcoil canister, you can maybe find a 79 or 80 with the air filter case still on it. the charcoil on those are on the lid of the air cleaner. might help a little. those are all i can think of to help you out. you might wanna post something in the N/W section also. some oregonians might know something else for there emisions. good luck.


and yes those are custom vents, just something different since i got rid of the scoop.
they look better here.https://www.rx7club.com/attachment.p...hmentid=106414

 

It amazes me how many people do the rats nest removal and then come running back when it's time to pass emissions wondering what the hell there gonna do. I wonder if these same people can be coaxed out of an airplane without checking to see if they actually have a chute first, lol.

 

hmm i wonder would a second cat help? with air pumping into both... sounds liek the air pump couldnt possibly doing its job with those figures lol...

 

Passing emissions testing is not rocket science. My 84SE was tested this year with a header/presilencer and easily 'blew' almost 2x the legal limits for HCO and NOx. The next weekend, I put my stock exhaust manifold back on (84SE, btw) with the 2 mono-converters and the cat, and it easily went well below the legal limits - passing me without any other problems. Incidentally, the hardware test (airpump/canister/cat) visual test was passed on both tests - I guess the guys don't think that big, chrome 2-pipe header and chrome presilencer look odd(!).

To pass emissions on these cars you need; a working cat (not clogged), air going to it from the AP, clean oil from a recent change, fresh plugs with no fouling, a clean air filter, and a lean mixture through the range. The mixture screw on a stock carb is below the carb body pointing toward the driver's side of the car - a 'hunting' idle is a good sign of a lean mixture. The rest is carb-controlled. Pre-mix will result in unburned oils in the exhaust which show up as HCO. High octane fuel will also increase emissions due to unburned fuel in the exhaust, increasing NOx and HCO...

In addition to these basic features, you can also improve test performance through the following;

1) Inflate tires to 40psi (IF RATED AS SUCH) to reduce rolling friction,
2) Turn off A/C and other accessories which draw current,
3) Fix dragging brakes which will increase drag,
4) Replace cap and rotor for clean emissions (check timing)
5) Replace spark plug wires (and plugs, always a good bet)
6) Rev the engine from time to time while waiting; this will help to blow out any buildup of fuel which collects around the seals,
7) Go early in the morning when intake air temp will be lowest,

Good luck,

 

Leaning will cause the H/C's to go higher. Lean means misfire or unburned fuel. This is what raises your #'s. As far as the Air tube to the cat, is the exhaust check valve
still inline and if so check to make sure that there is no exhaust coming back to the engine. Do you have the ACV removed and blocked off? If you have a huge street port it will be hard to get the #'s down. You need to have the precats on the vehicle plus the main cat. With a street port motor and a stock nikki i would think that the jetting would be way off causing it to run lean. Does the car jerk slightly if you are in say 1st or 2nd and you give it throttle slowly? rx7doctor

 

Yeah well.... he bought the car like this...
The pump is ran directly into the split air tube, bypassing the non existant AVC. Its got no rats nest or any ability to properly connect one due to melted electrical connections and I really do not feel like soldering good ones in or changing harnesses.

Looks like one of our friends out of emissions testing will be buying this car .

 

*sigh* I'm buying a car to register it... but my car isn't even registered... sad day
