Hey guys, I recently got a 96GT. I've had an 88GT for the past decade and had plenty of stuff done to it so I know a thing or two. I don't know a whole lot about the 4.6 though. I have an engine light on, codes are P0171 and P0430. I did some looking and found that the vacuum line to the FPR was broken so I replaced that. Figured I may as well change the plugs since I just got it last thursday, so as I was taking them out I noticed that all but two had a lot of oil on top of them when I removed the plug wire. The number 4 plug had a ton of coolant sitting on top of it, but the guy i got it from did say his heater core hose burst and he replaced it, and it is right above that plug so I'm hoping that's all it was. Anyway, what's the deal with the oil all over the others? Valve cover leak or intake leak? I'm hoping the vacuum line was why I had the P0171 code, haven't reset it and driven it around to find out yet, it needs a clutch which I am gonna do this weekend. Any ideas on the P0430 code? The previous owner said it was an O2 sensor, he replaced one but it was the wrong one. He didn't seem like the type that could diagnose anything so I figured I would ask you 4.6 pros for some advise. Motor seems strong, but drivability is crap due to the clutch so I won't know more until I replace it. Oh, and I was gonna go with a spec stage 2+. Anyone think of any clutch I should go with instead?
