IDLE PROBLE on my 93 chevy silverado?HELP?
I have a 93 Chevy silverado everytime i turn the engine the RPM goes up to 2000- 1500 and then slowly goes down to 1000 after 5 10 seconds...wen im running the truck, suddently the check engine lights turns on. when the light turns on the truck will only runs 30 mph ..i step on the gas pedal to accelerate but it wont run more than that..so i pull over and park the truck wait 5 minutes and then the check engine light turns off..and the truck will run just fine...
