Today I start the car and after about 10 minutes notice the SES light come on.The code im getting is P0172 (system too rich), and I was viewing the ltfts and noticed them hovering around -18.0, to -20.0 at idle. What could be causing this? I did remove the tb screen, but that was about 2 weeks ago. I have already ordered a replacement one from the dealer a couple days ago. What should I look at first?

Thanks Guys

Nick,

If you want to stop by during the week we can take a look at it for you.

Do you have a fuel pressure gauge? To watch fuel pressure?

Thanks,

Joel

Joel, I will probably take you up on that offer, although I dont have a fuel pressure gauge, any place I could get one or borrow one that you may know of (i.e. AutoZone).. I know the LTFT's seems to be wacky and im getting some part throttle knock, and too much full throttle knock with a 3.4, and the mods listed. Also when going "illegal speeds" the car wants to cut out at about 4.5k in 3rd. The knock is not false as I verified with some 100 octane though.

FWIW I do have the zzp rewire, but not installed. :ph34r:
