This car belonged to my grandfather. It has 79,000 miles on it. For the last year or so, it would begin to stall & my father would take it & have the fuel injectors cleaned out. It would go 2 or 3 months & start again. It only stalls after you have been driving it for a while & it is idling at a light. It starts right back up until the next stop. We had the fuel injectors cleaned out again, spark plugs changed & NO check engine lights are coming on. Any things we haven't thought of?
I had the same problem with my 1994 Pontiac Sunbird.
