I called my tuner up (who is also a mechanic) and told him what happened when I crawled it home and he had me check my MAF (which was unreachable since it was in the right fender and I just installed an Anderson power pipe ) and then plug in my Predator handheld. No CEL light were on so he had me do some checking around in the Predator and than told me to check my coils and my fuel rails. He also had me unplug a electronic device in the middle of the fuel rail that was attached to a hose and told me to turn the car in the on position because fuel would shoot out of there when I did for a second but when I did nothing happened. As of yesterday the problem just happen to go away and the car is now running fine!? This has me baffled. I know this might be a tough one to crack but if anyone might have a clue as to what happened I would be very grateful. Thanks always guys!!!
Sounds the exact same as what happened to my mustang. One (or most likely more) of the coil on plugs are going bad, or the boots are worn out/leaking. My car used to sputter real bad and miss when i would hit puddles or drive in the rain or anything like that. I could not figure it out it would just go away after a day (water dries up).
After a while the COPS will short out and it will always do it though, i just replaced all of mine with accel aftermarket ones and it runs like brand new.
