Engine shuts off.

[Jaegermeister2k]

The engine light is always on because of the off road x pipe,but it did that before i got the x pipe.Also i can idle and rev all day long,no problems at all,so i'm glad it's most probably not the fuel pump.I don't have the k&n,but i removed the silencer on the stock airbox,i don't think that had anything to do with it though.I'll chack the maf sensor as soon as i can.Problem is i can never tell if i fixed the problem or not,because it has only happened 3 times so far.

Here's another thing though.I was driving with the a/c on for an hour or so,and my car shut off,so alittle later i had a friend in my car,and i tried something.I turned the a/c off,and on like 3 times in a row,and the engine shut off again.It was the same kind of shutting off like when i normally drive.But it can't be the a/c because the engine shut off 1 time without me even using the a/c for days.I live in florida,and it's hot.But i still never use it.I don't know why,but i just drive without it.
