Your grounding somewhere. Start looking at the starter. Good luck.

Possible deposit buildup in the throttle body and specifically the IAC (idle air control chambers).This causes disturbance and your systems ability to control air/fuel mixtures at near idle conditions .Perform service, recomending removal of the IAC valve and cleaning with an O2 safe injection cleaner.3M makes a very good line of products including 3M"do it yourself" fuel system tune up pn#8963.Also verify proper EGR operation and no sticky valve or build up there.....good luck

follow the pipes from the cat forward, you shld be able to find them. from the cat down or back, would be your rear sensors.
