:1zhelp: Well guys im a noobie but thats beside the point. The point is i just bought this supra and i have already changed out the clutch and i had to rewire the knock sensor. Well the problem is that when i ease on the throttle and get it to about 3 grand it drops to about 1 grand then goes back up from there. I dont know much about these sensors and the egr but i know they have took off the charcoal canicter and the bvsv but would that cause it to run that way?
