I changed the fuel pump for one of HF jobs. No change! The engine still runs rough below 3000rpm. When I had that problem before it was much worse until I changed the MAF. If I put my hand half over the MAf intake (once unbolted from the air box) the engine speeds up and runs better. If I pitch the fuel return pipe the engine speeds up. To me it seems to be not getting enough fuel. If I diconnected the white wire (heater) on the O2 sensor the engine runs much better but still seems to be a little down on power.
With the wire white connected the engine is really dead below 3000rpm then picks and runs well.
What does this white wire do? will screw up my ECU when disconnected?
At this rate competing at Rim is looking a long shot.
Same sh!t different day!

I have not checked that yet. Maybe I should buy a scam tool and check or grab the book and figure it out. I would figure seeing as I've disconnected the white wire that the error will be the O2 sensor. If I get time today I will check but my wife is on my case as I only come home for the wekends and spend most of the time on the car......not good. Mind you I did suggest she took an interest and tried to fix the problem!

I couldn't find the wire to check the codes. A friend said it was the green plug that I connect but when i did it just sent the electics crazy. I'm almost sure it's fuel/Air ratio thing . I put my hand half over the MAF intake and the engine runs good. So maybe the white wire coming off screwed up the MAf or ECU. I plan to swap out both to do a test.

Josh has a write up for checking the codes on his site:

it's under notes and tips -> engine related
Hey I was going to PM you this week to see if you were going to be at rim and stuff.

Jeremy,
Fuel filter is new. MAF is clean. Ground? mmm I will have to check. The thing that puzzles me is it runs OK if I put my hand half over the MAf intake. I has to fuel/air ratio but as no one has any solutions.
