Ok so if anyone here can help me figure out whats wrong i'd reall appreciate it. I have an 02 gt with lt's,o/r x, slp lm1's, Intake 70mm tb, plenum, tb and plenum spacers, u/d pulleys, egr delete, and some other stuff. Well the problem is that after running for a little while it starts to sputter, bog and almost die. Somnetimes it does die but fires right back up and runs fine for a while. I'm thinking maybe fuel pump. When i got the long tubes on i had to extend the factory o2 harness. Maybe thats causing the o2 sensors to read wrong and it's trowing off my a/f? I have no idea. Anyways hopefully someone has heard of this before and can give me an idea. Thanks for any help.
