'89 Silverado stalls at traffic lights
Hello Folks I need help. I have a stock '89 silverado, 305 TBI engine 700R4 trans that often stalls at traffic lights when warmed up. Also will stall in parking lots when steering wheel is turned to lock. Running A/C makes it happen more often. Only bad when warm. Otherwise runs just fine gets decent mileage. 185,000 miles.
Problem came on gradually starting about a year ago. Kept happening more and more often now happens almost every traffic light unless I shift into N then maybe it still stalls about 50% of the time. It seems like when I pull up to a traffic light and stop, the engine idles lower and lower until it stumbles and finally stalls. In the last two weeks I replaced:
Any advice on what to check next?
