CEL when decelerating
hmm i checked codes and got the barometric air pressure sensor..what in the world is that o.0 also my cel comes on lets say im on a free way..then i slow down, when the rpms are dropping the light comes on. I tap the accelerator and it goes away. is my vaf going? this started happening after i put in my cone intake.

Re: CEL when decelerating
check your pcv valve or the o2 sensor.. is it in all the way? that could cause your engine idle really low and give out,
Re: CEL when decelerating
It compensates mainly for variation of pressure with altitude. It's built into the ECU, so repair = new ECU.Originally posted by hgallegos915:

Re-shaped and re-sized gearshift lever. Best driveability mod you can do!

Re: CEL when decelerating
my amp was being left on... and the cel light would turn on because the battery was way to low..my thoughts....i fixed the problem and i have no more cel light come on...those were some weird codes it trows...possibly I do need a new ecu. I feel its not as fast as it used to be.

Re: CEL when decelerating
If the voltage supply to the ECU was low, any amount of weird things could happen to a perfectly good ECU. It is not designed to work under those conditions.Originally posted by hgallegos915:
