wot is fine though and builds full boost also

 

bump for a solution

 

If the car goes into open loop in WOT, thats prob. why it runs fine there.

 

ohhh ok, still no fix yet to my problem I check all the connections in the wire again

 

I checked the connection goin to the ecu and its in there fine and all the wires going into the harness for the maf are fine also???? Im really at a complete loss right now

 

check for intake air leaks arond the maf/throttle body area. the fuel pump being noisy could be a sign of other issues or it is working harder. what setup do you have? stock box or open air intake? if it was fine before you messed with it, then something isn't hooked up right. especially if the maf swap worked on your buddys car. more info please. good luck.

 

What kind of test did you try? A voltmeter does wonders. Your codes lead toward your MAF, and the fact that it works on other cars leaves only the wiring.

 

well i finally fixed the problem the other day. I dont even want to admit it but somehow when putting it all back together i switched around my couplers and put it on backwards. Dont ask me how it happened but it did. i felt like a total tool but it actually took me a few beers in the garage to find it out. So if this happens to anyone in the future maybe its just backwards

 

No worries. Glad to hear that you fixed the problem!

 

Wow, that will do it.
