Question about 1985 Chevrolet Cavalier
When i crank my truck it runs wide open for a minute or so
and then it starts to idle down what causes this. it is a 1992
chevy S10 v6 I have a chevy Cavelier 84 and it starts ,and idles very fast and when i put it in gear it runs "normal" not as fast . But when the engine gets to about 190*) to 220*) the car stals after I put on the brake and then it wont start again until it cools down. I am a female and I am thinking it is somthing to do with the thermastat,or transmission problem?
Sounds like a vaccum leak at the throttle body or the intake. check for loose lines hissing with the motor running. Had a brake booster line come loose on my 92 and it ran at about 3000 rpms.

This problem is commonly caused by a dirty automatic idle speed control valve and throttle valve but always run a OBD2 fault code as well as the cleaning procedure. Buy a can of throttle valve cleaner (do not use carburetor spray cleaner!) from NAPA or Carquest (made by CRC chemicals) and spray it into the air intake while the engine is running, use up about 1/2 the can, engine will try to stall hold the speed up, shut it down and let it soak for 30 minutes, restart and blow out the remaining fluid, shut it down and disconnect the negative battery cable for 5 Min's to reset the base idle control
