2003 Chevrolet S-10 Repair Question
Mileage: 44,000 miles.
Sometimes my PU upon starting -the idle drops way down & wants to stall. Any ideas?
If there are no codes, take a look at your throttle plate, if it is real dirty take an old toothbrush and some air intake cleaner and clean the throttle plate and bore, see if that addresses the the idle issue. If it doesnt your going to have to take it to someone that has a scanner that has live data to see if anything is abnormal, paying close attention to the throttle position senosor or IAC valve.
