So ever since i've gotten my car its been running lean and i hate it. I've pulled all the plugs off and checked them and their a copper brown color. not too sure what that means but i changed them anyways to be on the safe side. Recently i've changed the distributor cap, roter, o2 sensor, and fuel filter. I've been looking forever for a solution but just cant find one. recently code 32 showed up about the egr, but its still running the same as before. Can anyone give me any ideas what can be making my car run so bad? it seems to run ok sometimes but then just completely loses power when i try to floor it.
