Hi all. I have a 97 Mountaineer with the 5.0L that has 140k miles. On cold weather start, it would either off idle or stall out. I dropped it at the dealership. They tried the IAC with no change. They tried a new MAF, but it only cleaned up a little bit. I had them do the pressure injector cleaning, but it still seems hesitant. The plugs and wires are about 40k miles old. I haven't changed the fuel filter, but I don't know how cold weather would affect that. I've read about the 4.0L intake issues, but I wouldn't suspect that on this.
I'm curious about vacuum leaks, but not sure where or how to check. I've also noticed threads on that sea foam stuff. How does that work?? I recently replaced the thermostat and temperature sensor on the top of the intake. Does this motor have an air charge temperature sensor on the intake?
Thanks.
