Alright, I'm just about to change the pump but am having doubts as to what it was.

Code 43 flashed (o2 or fuel supply system) . are these ****** codes ever wrong?

I seem to be running rich. Carbon on O2 and spark plugs. Changed filter and O2. I dont think it could be the fuel pump. AND the regulator's spitting out gas.

Fuel supply system is the Fuel injectors, pump, regulator, and filter. BUT NONE seem to be the problem.

The car runs rough, idles rough, and loses power at WOT.

the fuel pump relay works.

Im gettin sick of this ****. ANY thoughts?!

thanks a bunch.

What's your fuel presure? Is it within spec?

I would start by fixing this.

Isn't it supposed to spit out gas? I put a hose line on the end of the FPR to see if gas was making it through or if the stupid diaphram was stuck....and gas was making it through. So that would prolly indicate that it's not a bad FPR. lol ****, i worded that wrong

BabyDaddy

word lol...

I don't know dude. Been thinking about it but so many variables. Do all the plugs look the same or is one or two worse than the others?

even though it flashed a (43) u check ur ignition compoents. Loss of spark with result in power loss. Cap, rotors, wires????? gotta look at everything

Well here's an update but first, I'd like to thank everyone for the replies!

Well, it's not fuel.

I changed the Filter, Pump, injectors checked, Regulator checked w/working one, O2 sensor replaced.

I'm checking timing now Interesting, I was driving it tonight and at WOT only it would loose power. When it was at half throttle, while It was at half throttle AS SOON as it hit 4000, STOP it wouldn't go past 4000.

Thanks again for all the help guys.

Well, the theme is "always expect the unexpected"

Checked timing. Timing belt's off 4-5 teeth. Have it fixed tomorrw. THANKS FOR ALL THE HELP! I led everyone in the wrong direction i guess lol. SOrry bout that

How were you able to tell for sure that it was your timing belt that skipped some teeth? I am having a similar problem right now... car runs really rich, idle surges and stutters sometimes, and it doesn't have much power all around. I checked the timing a while back and it was extremely advanced (way past the white mark towards the front, i estimated about 22 degrees.. I backed it down and the car runs a little better now, but I'm also getting CEL 43 every once in a while and have all the other things you described.
