i looked over my vacuum lines and the hoses on my fuel regulator and iabs were switch and some of my problems went away but my motor is a gsr so it might be a little different. i have a wierd thought my tps is messed up, everytime i unplug it, it runs fine but with a lack of power. i still get a cel # 17 every once in a while i got one today. i honestly believe that my enegine harness is wired wrong. dont think if i got some kind of enigine mangement it would fix my problems.
