The PO85 means that the throttle is open too far at idle. It could be that carbon needs to be cleaned away from the thottle plate and bore, you need to adjust the isc motor or the tps, min air, and idle learn procedures need to be done. To describe the procedures would be lengthly and complicated. It would be best if you got a shop manual and followed the procedures or subscribed to all data online. As for clearing the codes goes with the key on or engine running push off and warmer on the climate control panel until it goes into diagnostic mode. Then when it displays PCM? push the hi fan button. Continue to push low fan until it shows clear codes...then push hi fan and the code will be erased. Then turn off the key. Maybe changing the isc motor and clearing the code will be all that is necessary and the code and light will be gone. Hope that helps.

Codes are reading low tps voltage, mapps high voltage ignition on low voltage at idle. Idle surges sputers and stalls when driving. Replaceed mapp and tps with no improvment?


Have you consider to check the battery power. I believe the main problem you have is either the battery or the alternator. Due to these two things with low voltage the brain ( ECU ) does not have the enough power to work. Good Luck.

My 1992 chev lumina apv van stalls everytime i put on the brakes at every red light it restarts after no codes are coming up what could it be?:


check to make sure the power brake booster is not leaking, do this by starting the van and just let it idle in park and push the brake pedal if the engine stalls or surges or you hear a sucking noise under the dash then replace the power brake booster if there is none of these systems then replace the idle control motor. GOOD LUCK
