you need to clear the CEL. disconnect the battery and wait a few minutes.

You could buy cheap OBDII scanner on eBay as well.

It takes a couple drive cycles for the CEL to turn it self off or you can just do the battery thing.

give us a cel code please!

laythor

the cel might not be related to the exhaust. just because it came on during this time it could be from something else.

CyberPitz

Find out what the code is, then. It may not be the exhaust. Also, do they fail you if your CEL is on?

italianman1987

for sure they dont pass you if cell is on.. how do i find the cell code? do i need an obdII reader?

you can do to autozone, oreilly or advanced auto parts and have them scan your code. Yes it is an obd2.

to lazy to read through the other posts... but the battery reset thing no longer works (in tx atleast). If you take your car in for inspections and they read the computer has recently been reset its a fail, atleast it happened with me
