I have a '94 GT. Only mods are BBK CAI, BBK 70mm throttle body. I'm having two issues:
1) Every time I start the car, after about a minute the engine will dip then rev to about 1700 RPMs then drop to normal.
2) Car is running rough in low RPMs (800-1800) and will throw a CEL until RPMs drop back down for 20-30 seconds. No CEL at higher RPMs.
Ran codes and got the following:
KOEO- 636, 332//172, 173 in continuous memory
KOER- 116, 636, 172
116- Engine coolant higher or lower than expected
636- Trans oil temp higher or lower than expected
332- Insufficient EGR flow
My main questions are on how to handle the 116 and 636. Thanks for the help!
