runs like crap won't pass 3k rpm, runs to rich and when reved to lean. also no power in it throw code 12 and if i reverse the pin a11 and a6 also throuws code fouty someting, to do with o2. any who does any one have a similar problem or a solution to this problem any help is apracieated.

won't pass 3K?? you're in limp mode. something went wrong with the installation is my guess.

when you soldered in the 4 pin connector into the ECU, did you put it on backwards??

i've had someone do that before, and had to desolder it and reverse it.
