Rep Power: 308 NO! a Diagnostic is about $50 and not necessarily going to pin point your problem... If the parts/repair shop does not want to read your code for FREE then go somewhere else.
I have seen a lot of stores in my area that are no longer reading codes for free... the bastards. ..
btw good post street... he covered everything I was going to see...
My guess would be it may be an air sensor related to your modification... or just a blown sensor somewhere...
However you do need to get that code read and find out what is throwing the code. It could be something more serious. Even if you can get a shop to read the code and just tell you the code number... you can look it up on the sticky for OBDII codes in this Tech Stuff board. And someone here may be able to help you with that.

Rep Power: 308 Yes you reset the ecu by unhooking the negative for about 10 mins.
which u should do to make sure it's the gas cap, and that someone just didn't steal your gas last night >=/
Basically the fumes in the tank build up pressure that if are not present, it trips a sensor.
