Car runs like crap until warm. Battery was disconnected but I plugged back up and ran the codes anyway... I have just replaced the IAB and TPS. ***UPDATED*** I changed the ECT just in case, changed dizzy cap and rotor button, set the TPS to .98. I did the diagnostic again. This time I got results. KOEO 11 KOER 21 ECT 41 Passenger O2 Lean 91 Driver O2 Lean 33 No EGR (duh) 18 SPOut circuit open 13 Idle too high I revved to 3,000 RPM 2 2 Which I'm guessing is Cylinder 2 didn't pass the balance test?
