my car is idling very lopy, almost like it has a custom cam, at 500rpm in drive at a stoplight the tach starts vibrating, and the car feels lopey, and the vac gauge is right at 12 hg, where its normally at 20. and i am also getting a check engine light when leaving stoplights
here are the codes and what the autozone 'puter says about them
1. 118- coolant temp sensor signal is erratic or intermittant (possibly from coolfan mod)
2. 563 problem detected in electronic high speed fan or ircm (coolfan mod again i would guess)
3. 189 left oxygen sensor is sending a high signal which means running rich
i have also gotten a 176 before (like in august) which indicated left o2 sensor running lean.
any help appreciated
btw when i say "coolfan mod" i mean that scott cut one of my ircm wires (14 or 17, not sure) and ran it to ground so that the high speed fan comes on with the ignition.
