problem with new itg cai - LotusTalk

toyopet · 06-11-2005, 09:46 PM

hey guys,
just got done installing itg cai and immediately noticed a problem. at around 5-7k rpm, the car has some hesitation. but below or over it, its' running just fine. any one of you encounter the same problem? any suggestions? thanx.

I have the ITG and don't have that problem.

I'd check the vacuum line caps provided with the install kit to make sure they didn't come off. If they were okay I'd probably look at the MAF sensor next. The o-ring on that thing is tricky to get right.

(Disclaimer: I'm not a real mechanic I just play one in my garage.)

I also have one and have not had any trouble. Actually, I think it is awesome!

No hesitation with mine that I know of. So far I have only had it on for 150 miles but I now have the above code on and I am not sure why.

Does anyone else have this problem?

I am going to call my dealer tomorrow.

Take care,

mr t

No problems, more than 2000 miles with my ITG cai.

I'd agree. Sounds like it could be a vacuum line/cap issue (especially the CEL problem) -- that appears to be one of the tricky/delicate areas of this install.

looks like the maf isn't positioned properly in the intake tract, and causing the evap cel.

The vacuum caps were double checked and the MAF was very carefully installed. If there was a installation mishap, the check engine light would not have taken 150 miles to come on, right?

How long do you need to have the battery disconnected to reset the check engine light?

Does anyone think that the problem could be related to the reprograming of my ECU at my 1K service?

Thanks all for your comments,

CEL would not necessarily come on right away -- it generally takes several driving cycles for it to come on, as well as go off once a problem is resolved.

The battery need only be disconnected for 10 minutes or so.

I doubt your problem was your dealer's reprograming of the ECU.

By any chance, did you get gas during this time frame -- could it be a gas cap issue?

mr t · 06-14-2005, 09:02 PM

Hi Jack,

There was never an issue with the gas cap. I always make sure it goes on correctly.

After driving for two days, The light went out on its' own so I really don't know why it came on in the first place but I am glad that it is gone. I guess it cycled thru it like you said.

Thanks for your time to input your thoughts,

Take care,

mr t

If you're curious, you can still view the reason for your last Check Engine light with an OBD tool. You can even view the engine parameters at the time it decided to throw the error.

If you're curious..

toyopet,

are you still having problems with hesitation? Have any of the suggestions noted in this thread helped you? These guys are awesome. I would have suggested the same things!

mr t · 06-15-2005, 11:08 AM

Thanks Ground Loop,

For the advice, If it happens again I will be REAL curious but for now, I'll just have fun.

Take care,
