After spending $375, the new fuel pump does very good. I put a fuel pressure gauge on the engine and even running at idle I get 46 psi. It was worth getting a Delphi for peace of mind I guess. I'm going to replace the fuel filter( been 3 years maybe a little less) and the fpr which I know is still factory. That could be causing my little 'misfiring' at the exhaust. I got a new one and its just a mtter of putting it on. I shoulda done it when I had the plenum off checking the injectors. Those Felpro gaskets really hold up more so than those paper ones.
