I upped the pressure to 44#'s and the code went away. But now I was getting code 44 (right thermactor inoperative) and I read in a bunch of posts that they usually got that code and replaced the TFI and the code went away. Well, I changed the TFI since it's stock anyways and the code did go away, my low end (1000-2000rpm) seems to have improved and my idle stays at about 950 alot more. But now I heard some louder ticking/knocking and when I pulled the codes I got 91 (left HEGO sensor indicates system lean). What do I do now? bump up the fuel pressure to 48+?? How can I find out whats causing it? Maybe some unmetered air coming in? Need help here pleeeaaaassseee...
