failed e-test - 88 N/A
So after driving my new car for a week I took it for an e-test today.
It passed on everything except HC ppm while running, reading was 81 and the limit is 66. I'm thinking that it needs a new o2 sensor. Thoughts? Advice? I drove the car on the highway for about 25 minutes before the test, it has new plugs, previous owner replaced the exhaust including cat a while ago and the car wasn't driven since. I think it's been sitting for a long time. I'm running 87 octane petro canada gas. |
How old is the cat exactly ,because Rotary engines have higher exhaust temperatures and Eat Cats faster than a piston engine..I went through the same Crap in a different Pile(loosely put..LOL)..I sent you a pm with some info I found while Tryin to pass myself..Others will post Too,be rest assured,you are not the only Owner that hasn't passed the E-Test..As a matter of Fact,I think you did rather well,considering this is your First crack at Rotary engines(Golf clap!!)
|
When my o2 was shot, it was wayyyyyyyy more off than that, but my 88 needed an airflow meter to make it pass, i was very close like you, so i would try that first. also, make sure your tps is good and set, that should help too
|
high octain would help to, not for power, but for the lower amount of bunk in the fuel
|
along with high octane u say the emissions were to high while at idle?... just lean the mixture out and it will pass ... same thing happined with my 87.5 ......
|
everything passed by a fair margin at idle, and everything passed by a fair margin while running except the HC ppm.
|
Ahh, i had the EXACT same thing on my TII. Now, what i did to pass was Go to crappy tire get the "Guaranteed to Pass" stuff. Run you car till almost emety. put in about a 1/3 of a tank of any Supreme gas (i personally used Sunoco 94). And then pour that stuff in. Run for about 10 minutes. And immedately go for your test and KEEP THE CAR HOT. (if your gonna wait keep reving and what not (call ahead like how i did and make sure the spot is open and ready for ya)). Also when running your prevous gas out take the car on the highway and drive it hard, get it all nice and hot. That worked for me and i passed with flying colours.
PM me if you need any more help. |
I used some camping alcohol in about 1/4 tank of gas on my 84 that I sold 2 years ago, passed like a prius. Just make sure to go to the gas station and fill the tank up to dilute the alcohol after the test.
The camping alcohol that you can get in Canadian tire is 99.4% pure alcohol. Works like a charm. Just be carefull. Adam |
I put a new O2 sensor in today at lunch time, back for the second test tomorrow AM at 10!
|
Well????..How did it go?..Did you pass?
|
Still no luck.
Got rid of the 10W30 that was in there, put the proper 20W50 in and will drive it for a few days to get rid of the 10W30 that is lingering. Test again on Thursday. |

20w wont do a thing, other than cause extra drag on all oil lubed sufaces.
|
I have to agree with Adam on this one.(..camp fuel,methyl hydrate..denatured alcohol..J-Rat's Recipe).Post your results..let's have a look at what your readings were ..
|
do (slow) 2nd gens like yours have air pumps? I routed the air pump of my SE directly into the cat when I failed the first time. they didn't look under the hood, and passed me no problem :) it aced everything the second time!!
I have most of the hoses still if you need them... |
Yes there is an air pump and air tube to the cat. I'm going to spend some time tonight going over everything with a fine tooth comb.
There is only one cat on the car too... Aren't there supposed to be two pre cats? |
Well... failed for the 3rd time today.
Here are my results: Test #1 running HCPPM: Limit 66, reading 81 FAIL CO% limit 0.37 reading 0.23 PASS NO ppm limit 757 reading 123 PASS test #1 idle HCppm limit 200 reading 74 PASS co% limit 1.00 reading 0.10 PASS Test #2 running hcppm limit 66 reading 100 FAIL co% limit 0.37 reading 0.29 PASS NO ppm limit 757 reading 133 PASS Test #2 idle hc ppm limit 200 reading 118 PASS co% limit 1.00 reading 0.10 PASS Test #3 running hc ppm limit 66 reading 144 FAIL co% limit 0.37 reading 0.30 PASS NO ppm limit 757 reading 200 PASS test #3 idle hc ppm limit 200 reading 197 PASS co% limit 1.00 reading 0.17 PASS It keeps getting WORSE not BETTER Forgot to say that the tank was almost empty and I put a gallon of camp fuel in before going to the test. |
well there is always the bootleg etest option ... atthis rate all the money u are spending on little dodads to make it pass u could have had a bogus one already lol thats what i did with mine
|
Go for the conditional pass! You must make as many repairs combined up to $450 to pass. You need the 1st E-Test, a diagnostic test and a 2nd e-test to prove that you failed. For me it said that I needed a new Cat (>$400) and 02 sensor (>$400 from mazda). In other words it cost about $200 to get a conditional pass. The 2 tests and diagnostic are included in that $450 max cost. :)
|
no conditional pass for me, I just bought the car a few weeks ago so it has to pass.

That's odd. It worked for me on my 85 gs. HC were super high on first test, second test with the alcohol the HC's were almost nothing. This may have been covered, but another trick is to install a hose that dumps the air coming out of the air pump directly into the cat, by passing the stock system. This will dilute the exhaust enough with clean air and help the cat to burn the HC's. This may or may not work, sometimes they measure the dilution. It also makes your cat run hotter than a mo fo. |
I heard that unhooking the linkage from the throtle to the oil injector pump will help pass on the running test.
Does anyone know if this will damage the motor?(it should still get same oil as at idle) I might need to get one tested this saturday |
Ya, I've heard of that. Should help, but it sounds like his problems are more major.
Fried air pump? Dead cat? Worn oil seals? Hope you have better luck with your next test. |
Sounds like a tired cat. My 85 had no air pump and 10% alcohol in the tank was enough to pass it using a brand new cat.
|
Well it failed again yesterday.
I checked the cat and it had a small crack inside, so I replaced it. The idle tests were cleaner, the HC running test went down compared to the last test but not enough to pass. The CO% running test went up, and it failed on that now too. This is getting very frustrating. Can I adjust the TPS to lean the mixture out (less than 1K ohm when closed) ? Any other ways to adjust the mixture? |
Well, one of your problems is that, if as you stated you used Crappy Tire camp stove fuel, you put in neat naptha, which is light run gasoline, unadulterated.
You should have put in almost pure alcohol ! Try again, and use some of the other posters modifications. I know it aint easy, Dave |
And where do I buy this "almost pure alcohol"??
|
sunoco ultra 94 + 6 bottles of gas line anti-freeze!
|
one other thing you said that your tank was almost empty when you put the alcohol in, my '88 NA has a 63L tank but if I fill it when the needle just get's to E I still have ~10L left in the tank so you might not have been nearly as empty as you thought. how long after you replaced the cat did you etest it, cats need a little time to break in (couple days to a week). You're so close I'm surprised the new cat didn't pass you.

well well well
I discovered tonight that the metering oil pump was stuck on full open. I fixed it, and will take another test on Monday! |

It passed this morning.
Clean as a whistle. I didn't use any tricks. Now to find some longer 10mm bolts to hold my license plate on.... |
Congrats!
|
I'm having the exact same emissions problem as you logan. How do you set it? I see the haynes manuel saying how to take it apart but not set.
|
On an S5 car it's electronically controlled, so I don't think you can fiddle with it as much on an S4 car. Is your car an S4?
What I did, from under the car: - take the return spring off the actuator - disconnect the actuator rod - lube the actuator and work it open-close-open-close-open-close for a long time - reassemble and ensure that when I open it that the return spring closes it |
conrats Doug. we'll see you ripping round peterborough in no time...
|
damn mines S5.
|
No hope for me to pass, probably going to leave it in the garage if I can't pass the next AirCare.
|
Well just because it's an S5 doesn't meet the MOP can't be fixed.
Crawl under the car and have a look at it, it could be stuck open too. You'll just have to get creative to see if you can get it working again... |
Bogus E-test rules. I had the same problem on my S4 n/a it was the biggest headache.
|
I passed! I used that gurantee pass stuff and bought a new O2 sensor. Ripping it on the highway for an hour and redlining dropped my HC by about 33%, thanks for your help guys.
