    yes, lean will make it pop through the intake also. have you checked the egr and all vac and pcv hoses?

      Have you cleaned the MAF? Fords are notorious for getting a dirty MAF and running like crap.

      I still say it's probably something with cam timing or maybe an intake valve not sealing well. I worked at a retail repair shop for 10 years, worked in dealerships the last 3 years but not as a tech any more. While in retail I worked on all makes and models. Popping through the intake always seemed to end up being ignition timing, improper firing order, jumped chain or belt, or valve issues (not sealing, not closing all the way etc).

      I'm also saying that because you said it had a new head. Define "new"...

      I've seen new (rebuilt) heads have valves stick and cause funky issues. May need to run it with the valve cover off just to watch the valve train. I know, i'm reaching, but if you've checked everything then you may have to go to not so common measures.

        Ive checked all the hoses. However theres on that comes outta the vacum canister and leads somewhere under the throttle body. But i dont see anywhere it goes?

        Yes i did a compression test when i installed the new head and they were all around 160 i believe.

        Well i bought one from a machine shop cause the one that came on the motor had a melted valve and a hairline crack beside the valve. Ive cleaned the maf with maf cleaner and i checked the timing yesterday and its dead on. Its gonna be hard watching it with no valve cover. Cause the upper intake and throttle are over the valve cover..

                Im not sure. Ill have to check it tomo. But throwing the O2 code, wouldnt that be the O2 sensor causing it to go lean?

                  no, if it has a lean code, something else has happened to make it report that. if it knows its lean or rich, the sensor is working. if its stuck, ie not switching,that could be a different story

                    you have probably checked, but go over vacuum lines

                      Well after driving it an getting stuck in the field behind us. I finally got it out and it got a lil too hott. So now it's throwing a 116, 172 means hego sensor fault/lean, 211, and a 542. Suggestions? And I'll look for vacuum leaks. But I tried to find a diagram with no luck.

                        You are having a lot of odd symptoms and codes. When I see that, a lot of times I see a poor connection like grounds or a bad connection at the computer. I would check your ground from your battery to the body and from the battery to the engine very closely. I would also disconnect the PCM (engine computer) and inspect the plug and all the pins very closely.


                        So far the codes you have listed are

                        P0157 - 02 Sensor low voltage Bank 2 Sensor 2.... Look for blown fuse, bad wiring, bad 02. This is the sensor behind the cat converter. It has no affect on A/F ratio.

                        P0172 - System too rich bank 1. Having a vacuum leak and a rich code are contridictory... check fuel pressure, for fuel pressure drop indicating stuck injector, leaking FPR etc..

                        P0211 - Fuel injector circuit malfunction cylinder 11???????

                        P0218 - Transmission overtemp condition

                        P0116 - ECT range/performance problem (probably due to overheating it in the field). Saw this a lot when thermostats went bad

                        P0542 - Manifold intake air heater????

                              It's been so long since I worked on pre OBDII (no offense) that I just automatically think of things in OBDII...
