I just put in a stillen y-pipe and a placeracing CAI about a month ago. Now my car is burning super rich and it bogs at like 2500rpms. Did anyone have this problem or does anyone know how to fix it?

 

hmmm....did you reset the ECU after installing the CAI and pipe?

 

I say 1-2 for me.

1: Slip
2: Hesitate
All the other ones are very minor.

Try resetting your ECU by disconnecting the battery for a couple hours.

 

Reset the ecu and it still doesnt run right...If anyone can ask around for me and see because i have to go racing on the 30th of this month.The only other thing i can think of is to play with my throttle positioning sensor,and see how that works ??? does anybody know what the voltige should be on the TPI? Im guessing .5...

 

If the car is running rich, your O2 sensors should have picked that up and adjusted. Maybe they are the culprit? Seems unlikely though since you would have gotten a check engine light if they were bad. One suggestion would be to go back to stock and then see if it does the same. A trip to the dealer would be in order then.

 

I thought that but my check engine light would have come on...I took my plug out and it was BLACK.I give up, i think im going to go put in a order for a 2002 max

 

Have you checked the front O2 sensors by pulling them out? Maybe you should check just in case.

 

How would i know that its bad? is it kinda like a rattle(meaning its bad) or do i check the color? and if so what color is bad?

 

There is an easy check but I am not sure of it. Perhaps you want to seek out Daniel B. Martin. He hangs out on the 4th gen forum and will surely know the answer to this

 

Thank you for all your help (I owe you one)

 

no problem

 

I was thinking and there may be another reason for your problem. Have you checked the MAF sensor? If that thing is not working right, then that may be the reason you are running rich and the car is bogging. Try and take off the intake and go back to the stock box. If it still does it, go to the dealer. If it is the MAF sensor, it is not a cheap fix..... $400 or $500 for a new MAF tube.

 

That could be it because my car already went through two of them (dealer fixed it thank god) i might have bad wirering to make it keep happening. Just to be sure does your MAF sensor have the plug on the top? Maybe i but it in wrong?

 

yeah, it is the tubing that has the big plug on the top (MAF sensor)

 

Ok i did it right then.I was driving my car today and it kicked ***. The problem is tem. gone...(i always heard that if your car runs really well its going to blow-up soon)Anyways, the problem is gone for now, im still worried though. Wish me good luck!

 

hmmmm...if it is gone now, then I would definitely suspect that the MAF sensor is faulty and not working correctly all the time....

 

this is going to suck because I have to put on my stock y-pipe and my stock intake set-up so I can bring it in to get inspected. Err, I dont think im going to make this race the 30th...( by the way its doing it again worse now, I was going up a minor hill and it started to ping and tick and it was bogging)

 

good luck getting it fixed....
