Honestly, If I were you i'd take it to a profesional before you throw any more money at it than you allready have. As your wallet can tell you, your going about fixing this thing in the most expensive way possible. Tests are free. Replacing properly operating parts is not.
the fuel damper doesnt control fuel pressure... the fpr is in the fuel tank. i agree she should check fuel pressure. tests arent always free, most shops charge for diagnostics

Testing it yourself is always free..... And paying someone else to do a diagnostics check is still cheaper than throwing parts at it and praying.

well, i just changed the MAF after freezing my butt outside with a vomtr. i wasn't getting a reading at all from C-D terminals, so i chose the replace it. There is a difference in driveability it doesn't have shift problems any more, but i'm still seeing black smoke and it stumbles while accelerating on the highway...cat could be recovering from driving it around for a couple months while it ran rich.

Specifically, i've been running the codes using an obd2 scanner and getting P0172 and p0175....the 02 sensors in bank 1 and 2 show "rich".

Now, there isn't a check engine light after resetting the pcm, but i haven't really driven it more than 10 miles so far.

We shall see if i still have the problem. i brought the vehicle and asked them to check the pressure on the rail and they claimed it was high, therefore i changed the rail and fp damper.

IAT has proper resistance.
