Title: marshal's issues 87 GN
Post by: TexasT on May 05 2016, 07:02:10 PM

I went ahead and started a thread. I'll put a link in the shout box.

Lean code 44
I would be looking for a leak in the intake past the maf. If you are running the stock cloth maf to turbo pipe I would bet a hole has formed. I have used electrical tape in the past but a metal pipe or new cloth pipe might be in order.
Next you might put a gauge on it to verify fuel pressure. It is spring, probably time for a new fuel filter anyway.

Also the 1st Tech thread is Steve's site vortexbuicks so you should spend some time reading as it has a wealth of easy to find & useful info.

Do the MAF tap test, see if the idle wavers when you tap it
