i have a gsr motor in my 99 si boosted. i've taken my car to get it tuned but my car keep going into limp mode. according to what i've read on here, limp mode wont go past 3k rpm, but that not the problem with mine. when i'm driving my car it run perfectly until a check engine light come on and when it does, "my car loses power(wont accelerate) whenever i push the gas pedal," no matter what rpm i'm at. if anyone have any problem similar to this, please let me know how to fix this. thanks
