Sounds good, Thanks, will do!Concentrate more on basic issues. Stop worrying about the PCM relearning, that is extremely minor with these old computers. Only unplug them when you have to, not to erase anything, do that as a last resort or step. Skip the concept of limp mode with these PCM, they really don't have that from what I've seen. If it's running very badly, it is not due to the PCM relearning, or limp mode, it's an actual bad part, sensor, plugs/wires, or a wiring issue etc. I'd bet on wiring, a bad connection somewhere that affects many things, and thus generates multiple error codes. Unplug the main engine connector at the rear area of the bay, look at both sides and clean if any corrosion is seen, but put it back snugly. Check the bolt when you first loosen it, is it loose at all now?
Edit:
Argh, sorry, been thinking in bed - planning tomorrow's agenda, about what you said (to check.) Good idea, of course, and will (have helper) do, and certainly wires (reported loose or faulty wire harnesses too) might generate this multitude of codes...
...is the same logic thought to be possibly responsible for all the hesitating, stuttering, intermittent (but somewhat minor or fleeting) lurching and power acceleration drops as well? I hope yes, and will avoid the reLearning/MAF topic, but wondering about the misfirings I had one day also being a clue: Maybe I should also focus on getting another set of 8 plugs and wires?
