Help! Check Engine Light!!!

[96BlazeOrangeGT]

Yellow light came on yesterday. Less than 9000 miles on my '04.

I'm thinking about taking it to the dealer but worried about how they'll look at the mods on my car and tell me to F-off.

Mods listed below.

Anything here that will void my warranty???

Depends on your dealer.....mine would say, "you're fine", but it depends on how well you are acquainted with the service manager.

None of those mods, except "maybe" the catted X should pop a code or even be related to a code.

See if you can find out what the code is. Might be some thing as dumb as the gas cap not being tight enough. That's a common MIL my Father's dealership sees. Check that out BTW.

Can't you go to Auto Zone and have them check it for free to see what's throwing the code?

 

[96BlazeOrangeGT]

thanks for the input

going to A-zone today to have the code pulled.

gonna tighten the gas cap first though

I could be mistaken but I am pretty sure we have a seperate light that say's loose gas cap

you got SEL MILs on your rear o2 wires?

 

[96BlazeOrangeGT]

no MIL's
just the harnesses extended via Bassani's included wiring.

I would get the code scanned and make sure its not the rear o2 sensor error.
