Put the head on, timed camshaft as best we can. Still misfiring. Tried putting some seafoam in oil and vacuum line. All of a sudden it was like a snow storm coming out exhaust. It was catalytic particles. Found upper left pre cat to be gone as in a giant hole through it. Ordered the y pipe and...

After all the chasing of the different codes. It has come down to a dead drop on cylinder #5. Certainly not the direction the codes sent us. We removed the head and brought it to machine shop. They found a broken valve spring (replacing all springs on the head). Hope to re-install this Thursday...

Today we put on the new ford fpdm. It is running much better. The idle is still bouncing around 700-1000. We decided to disconnect battery for night and see if computer has to re-learn in morning. My mechanics i have known for the past 28+ years ( i am a P.O. And i am tasked with maintaining the...

Yeah, seems like alot. Have over 110,000 miles so plugs, wires, coil pack, and pcv valve and elbows were needed anyway. As far as fuel pump it was failing (when tested out of truck the flow dropped). The maf sensor was result of 2 garages that both told me that this would solve my problem ( they...

Fuel pressure was 40 at idle but bounced around a bit as idle changed. Tested iac with meter.

Was thinking of trying to replace the fuel pump driver module. Maybe that is going. It does look bad but I do not see any holes in the metal... When we checked the idle air control we were able to move the plunger. Seems to be okay...

Them codes cleared. New code that came up is 2196 (o2 sensor) believe we caused it to show up. Yes cleaned with appropriate cleaners IAC and throttle body

Hi, I have a 2004 Ford Explorer Sport Trac 4.0 with 110,000 miles. The problem I have is it idles low and the car shakes and wants to stall. It iniatilly threw codes P0300, P0304, P0305. Changed the wires, plugs, coil pack, and pvc hose with elbows. No difference. Changed fuel pump, no...
