Right off the top of my head, I would also suspect the idle speed control - best way to check it is when the engine is running, unplug it and see what the engine does. If it makes no change, you MAY have found the problem. If it changes the RPM, it is working OK. In the past, I have seen the PCM fail in that circuit on a Ford product.

It was re-engineered to replace the slight throttle opening for the hard stop with a calibrated hole in the throttle plate. This made it immune to the usual sludge buildup that was common on older fuel injection setups.

Well, although these tires were in good shape as far as tread was concerned, they looked real sad. All were flat, but new tubes fixed that. In addition to years and years of scuffing and fading, they had paint splattered on
