Hey just wanted some input on what u guys think might be wrong i jsut put in a gsr motor last night it came from my buddies car is has 2 bent valves but still runs mint jsut as fast as before it was messed up.i have full intention to replace the valves. now that it is in my car it pulls hard sometimes then other times it is slow as bags the only thing i can think of is that the knock sensor is hearing the knock then retarding the timing a lot. my buddy was runnin a p28 chipped so it wouldnt be looking for knock sensor. so it wouldnt be getting the timing retarted like mine. any help would be good thanks..
