what r the symptoms of a bad pcm?
Hey guys I have a 96 mustang 3.8l that im trying to fix right now.i have both running lean codes but i replaced alot of stuff and fixed all the vacume leaks. this is all the stuff i replaced. Egr,dpfe,o2s,maf,uper and lower intake manifold gasket,fuel filter spark plugs, spark plug wires, and the ignition coil. I pretty much replaced everything that would cause the codes the car runs great no problems jus the codes wont stay away. Thats why I was suspecting that the pcm is at fualt that and it never runs the egr monitor. So if you can help me out it would be much apreciated. Sorry if there is already one of these questions posted already.
