My car is idling at about 2000 RMP's, and the timing is so far advanced it's about 2 inches past the last mark. I set it to 20deg adv about 2 months ago and sometimes it would run bad and Idle high. Now it does this constantly. I checked to make sure the distibutorto make sure it wasn't loose, and it wasn't. I run 93oct gas all the time and have never had a problem. My thoughts are that a sensor is bad and causing an incorrect reading and the ecu advanced the timing to correct it. Has anyone had the same problen? I'm not sure, but I could use the help.

 

I could really some help please.

 

you can change the idle speed if its too high. It tells you how if you have a FSM, Chilton, or Haynes manual.

 

what is the idle speed??

 

2g's is running really high you want it at about 8 or 9!!!

 

Try unplugging the TPS, and reving the engine 3 times over 3000rpm. THis should lock in base timing mode. If that doesn't work unplug the IAC and AAC to see if the idle comes down. If it does then U know what the problems are.

 

My car went back to normal Idle on it's own, But sometimes it starts acting crazy agian
