HELP NEEDED!!!!
 

Installed Invidia N1 catback last night and this morning my check engine light is on. Is this normal??

no. check to see if you accidentally disconnected an o2 sensor or something along those lines in the process. the actual code it's throwing should help a ton in diagnosing the cause.

Gonna hook her up to reader at lunch. Thanks. Will post what codes come up. No o2 sensor diconnected

WARRANTY DENIED.

Just kidding man. A cat-back should not throw a code.

Yeah this has me confused as hell. Even the mechanic who did the install is stumped

This may sound too easy, but did you try a battery disconnect? Obviously you should get the code read tho...

I'm a little confused as to why the mechanic didn't pull the code?

He is a mechanic here at my shop. We work on trains and rail bound trucks. Gonna read codes at lunch.

No I didn't try that. I am thinking the ECU is flippin out b/c of loss of back pressure???????????

I'm gonna have to say that's a negative. I would imagine if this were the case that many people would have already experienced this issue.

Damn..................... I will post codes soon. Thanks for all you help!!

Cam shaft sensor, crankcase sensor. I think time to call dealer :cry:

yep that has npthing to do with the exhaust..

Bummer. You never mentioned one thing though: is it running strange?
