Mucho codes here - Yikes! I recently changes front brake pads and cut the front brake rotors. I disconnected the battery before working on the brakes.
My car runs like **** now. I'm throwing a ton of codes (108!) and my check engine light is flashing on and off.
This weekend I collected the codes and checked a few things; The codes were engine codes and "chassis" codes. Too many to list but some include:
Bank 2 fuel rail pressure too high
Bank 2 emmissions cat test - failed
****************
Anyway, I checked around under the hood and found a plug wire had come off the coil (passenger side - Bank 2). All other electronic connections (injectors, MAF, sensors throttle position sensors, etc) seem to be OK. I also checked the ABS fuses in both fuse boxes - no blown fuses were found.
I cleared the codes with OBD-2 software and ran the car for awhile with no issues. This morning I started the car and the engine check light went on again.
**************
Questions:
What are chassis codes - can OBD-2 clear these or only engine drivetrain codes; I suspect this has something to do with the computer that controls the ABS?
If I take the car back to the dealer I'm sure they will reset the ECU which I modified earlier with LS1edit. Is this a dumb idea?

My car is slightly modified; ported heads, SLP MAF, LT headers with cats, rear O2 Simulators, cam, etc.
Thanks....

Visual. make sure no wieres are touching and shorting out on the headers. The ground tab on the back of the engine is intact and the - battery termial is tight and not corroded and beat up
