Well found the problem, it was a vacuum leak plus plug wire not seated all the way. It was the big rubber elbow with the red plastic vacuum hose that had slipped off somehow cause I know I put it on. Don't know if it feeds the egr or what. Also the middle plug wire on the back was not seated properly. Purrs like a kitten now. It was very clear what was wrong when I opened the hood outside today. Sometimes you just really can't beat looking at something in the daylight! Thanks for your help guys
Brooks, does your black rubber vacuum elbow have 2 small red hard lines inserted into the bottom? If so, 1 runs back over to the passenger end of the upper intake to supply vac. to the evr (egr solenoid/vac. regulator). The 2nd red line supplies vac. to the fpr (fuel pressure regulator) on the front drivers side fuel rail. The sm. hard green vac. line runs from the evr to supply the egr valve. Did the red line(s) come out of the elbow or did the elbow come off the manifold port? If the elbow slipped off the intake port, you can zip (cable) tie it on or use a sm. hose clamp. Or pocket a snugger fitting 1 or 2 next time you visit a self service salvage yard. They tend to get ill-fitting with age, heat, oil, etc.
Yes it is the elbow with 2 small red hard lines. It was hard to tell there were 2. Didn't know what they fed so thank you very much for the info. The elbow just slid off the manifold and I think I knocked it off when doing the back sparkplug wires. It seems to fit well so I'll see if it stays on for now but thanks for the tips Sheila. This forum rocks!!
Brooks, that hard red line can also come out of a black rubber coupler under the throttle body causing a vac. leak and po171/174 lean codes. But, hands down, the most common vac. leak on your eng. is the pcv valve u-shaped hose under the throttle body. Ford is vac. crazy, lol!!!
