After driving the car, for say 15min., the car will give a quick hesitation or two then then eventually stall 5min later. I could be doing 55 on the highway or stopped at a light, doesn't make a difference. Car will restart but will stall 5 min later. After is stalls, I know i'm getting spark and gas so thats not the Problem. Dealer thought it was the engine relay, but it didn't correct the problem. Now they are saying its the Air Flow Meter. MASF has come up on this site as a possible issue but how can I tell which is causing the problem? Also I do have access to an 85 Maxima, can I use its Air Flow Meter?
