1999 Mustang GT stalling while driving!?!?!
Hi everyone. This is my first post and hopefully not my last. I have a 1999 Mustang GT with about 80,000 miles on it. Last week, as I was crusing down the road, my car stalled for no appearant reason. I didn't think much of it until it did it again like the next day. The last few days I have been swapping parts out to try and fix the problem but nothing I have done has fixed it. So can anyone help me? I changed the fuel filter, idle air control valve, throttle position sensor, and I have cleaned the MAF with MAF cleaner just in the past few days. I am not getting any service engine lights either. Could I possibly be getting a bad coil or maybe a bad MAF sensor? The car's engine is relatively stock. Just bolt-ons...BBK shorty headers, Pypes O/R X-pipe, Flowmaster cat backs, Steeda U/D pullies, BBK CAI, 70MM TB, Proffesional products upper plenum, Diablosport 93 octane tune.
