02 wrx cutting out at 4500rpm
So I just picked up my new to me 2002 WRX last night. Everything is great on it except that when I started driving harder last night, I noticed it is cutting out at WOT at 4500RPM. It almost seems like its hitting a govenor. It will cut out at 4500 then come back on and maybe cut out a couple more times until redline. This is obviously happening really quick. Sometimes it will cut out for longer like 1/2 sec vs. .2 seconds maybe.
I have done some research and searched on other forums. Here is my question. Is the aftermarket Cold Air Intake that I have causing this problem? I realize that intakes are not good for these cars, but this what was on it when I bought it. Otherwise it has a full Cobb Exhaust from the turbo back with no cats. I also have the Accessport tuner set on stage two, which says it is for full exhaust and stock intake. Do I simply find a factory intake and my problems go away or do I have bigger problems? Thanks for all the help. I also know that the spark plugs have recently been changed in the last 10k miles.
Does anyone happen to have a stock intake they would be willing to part with? Should I just get the $150 Cobb intake since all the Cobb stuff works together?
