Ok, I have done some searching but can't seem to find a situation quite like mine. So here it goes...
I have a 02 WRX with 52000 miles on it. Its completly stock and has always been that way. About 3 weeks ago I got on my car for the first time in a while and at about 5000 rpms the engine felt like it was completly cutting out and lurched forward, then caught again and accelerated fine for a little bit then cut out again. The engine isn't really cutting completly off but it just seems like it. It seems to do this in just under high boost. Now the problem has gotten worse in the past few days where after getting off the highway from work (about 40 miles) even under just a little acceleration the car does the same thing.
I'm thinking this has something to do with loosing pressure, because the engine runs perfectly fine under low levels of boost (cruising on the highway or under very light acceleration). Has anyone ever had this problem and know how to solve it or have any good suggestions. I'm really bumming about this because I love my WRX!
Thanks in advance.
