I just got my car back from the shop and now it is acting weird at WOT. Under normal driving it drives and feels awesome. Background: 2 weeks ago my car had a bad misfire. Turns out it was injector 6 that went bad. Took it to the shop this past friday and they put a new injector in( I know because I bought the injector myself) and as they test drove it the fuel pump resistor went out. So that got replaced as well. I was driving it for 2 weeks babying the crap out of it because its my only car. When im at full throttle it acts as if its starving, like surges of power and then no power. I dont have a scan gauge or wideband, im saving up for them though. So I cant tell you any numbers or anything like that. Basically my question is, is there something I can do to fix it? Like can I unplug the PCM or does it need to re learn on its own or what? I have a w body store tuned PCM. And before the injector went out the car ran absolutely perfect. No issues at all. What could be causing the car to do this? Im looking for help from you guys before you tell me to take it back to the shop lol
