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

D.T.P

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

93tegralsv

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

unless u guys know ppl for etest pm me

mike1787

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

Spydersniper9

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

93tegralsv

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

Spydersniper9

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

MPR

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.

Spydersniper9

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

MPR

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...

Spydersniper9

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

93tegralsv

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

93tegralsv

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

nizmo

iTrader: (7)

u sure u didnt advance the timing?

93tegralsv

positive , turned it towards the intake side

MPR

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

93tegralsv

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

nizmo

iTrader: (7)

u idiot!!!! LMAO!

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

MPR

Glad it finally passed, 93tegralsv.

93tegralsv
