I did an etest over the weekend and my car failed horribly, only on idle. the HC limit is 200 car was at 444 and the CO limit is 1 and car is at 1.09 . what could be the cause of this ? the cat ?

 

How many KMs on the car/cat?

 

Clean out your IACV, retard the timing as far as it will go (turn the dizzy back) and manually bump the idle up to 1000rpm and I bet it will pass. (can put everything back to normal after the test. It won't hurt the motor, it'll just be really gutless...lol)

Exact same thing happened with my car and that is what made it pass.

Good luck.

And oh yeah, is the CEL on?

 

411k, burns no oil. could it be the cat? thought the cat only affected the nox reading . cuz last summer it blew out through the tail pipe saw a bunch of metal flakes behind my car all over the ground. or would it be something else . the check engine light isn't on

 

Cat affects everything.

Do what mike said to do, if you fail, change the cat

 

Lol holy crap, usually people replace their cats every like 100-200K I'd change it, it's a cheap fix

 

the car has 411k, , cat's like 80k, ill just change it . found 1 for 80 @ Jdm addiction .

 

oh well that's really not too bad, what are your o2 sensors like?

 

Pay under the table......

 

unless u guys know ppl for etest pm me

 

hows the spark plugs/ air filter and injectors seems to be to much fuel going in leaking injector(s) or shotty plugs not fireing good or air filter pluged. going by those hc numbers and co

 

i do etests and most likely a new cat will help the HC's as for the CO you'd have to get a diagnostic tester to see the reading of the o2 sensor to be sure if its an o2 sensor

 

wouldn't the be a check engine light on if O2 was faulty ?

 

Only if it fails completely or stops communicating with the computer.

 

Ok, wow... to the OP: You failed HC at idle and CO by only .09... Retarding the timing will significantly reduce the HC and will also reduce the CO.

All you need to do is retard the timing and bump the idle up to 1000 and it should pass.

I went though this exact thing with mine and it failed worse then yours.

It is possible for the O2 sensor to be "slow" but not off enough to cause the CEL to come on.

But you shouldn't have to change anything. Just try what I said.

 

Is your car lowered if not you still have to worry about nox if it is lowered retard the time and take it to an above ground dyno facility because they'll do a two speed idle test (TSI) as the car cant get on the dyno without being damaged and you can't measure nox in a TSI. If you take it to an inground dyno you gotta atleast change the cat and always make sure you get the cat hot. How soon do you need the etest to pass?

 

PM Nizmo and ask him

if he can't hook you up give me a shout

 

Guy doesn't have to replace any parts or spend any more money except on another etest. Just turn the dizzy back and bump the idle up.

 

Ya he she def try that first thou ^^^ but I'm just saying what if it doesn't pass he spent another 37$ bucks when for like 70$ he can pass for sure...

 

Still he's gotta make sure that cat is hot cause if it isn't the hcs will be through the roof. I'll hook you up with a two speed idle if it's lowered

 

the front is lower and CT did a 2speed cuz car would practically sit on oil pan . need test done by 28th this month .

 

an epic fail once again , set timing back and it did worse than my first 2 runs went from 444 HC to 203 ( after changing cat) then back up to 454 after setting the timing back . wuts next

 

u sure u didnt advance the timing?

 

positive , turned it towards the intake side

 

Towards the intake ADVANCES the timing. Towards the exhaust RETARDS the timing.

 

did my etest saturday and finally passed , just added the guaranteed to pass stuff , drove around all night friday . and passed with 59 HC and .38 co

 

u idiot!!!! LMAO!

i told u if u RETARD the timing u would pass. Glad to hear you passed!

 

Glad it finally passed, 93tegralsv.

 

I asked you if I had to turn it toward the inside of the car and u all agreed on thursday

 

That's great that it passed man

 

thnx for all your help guys .

 

what stuff did you buy lol i could probly use some lol
