Alright, after doing massive research, i checked my knock and sensor. It was loose, very loose. It came off right when i grabbed the wire. Found out there was not a cliip to hold the plug to the sensor so i made one out of paper clips. Had the starter off, so i installed it back on and started the car. Vac went to 14 instead of betwwen 10-12. Reved it a bit, and it seemed to respond better.
Then i took it out for a test drive. Still lagging a lot and i know its running rich bc it smells a lot like there is too much gasoline. So i have the negative terminal on battery disconneted for the night. Will try again tomorrow and see what happens.
Also, when checking a j4 ecu, is it the same as any other ecu, i.e. turning the diagnostic screw (???) one time counter clock wise and turn car on without starting??? Can someone help confirm this?
