Fixed a LOT of loose connections, vacuum leaks, burned insulation and = much better. Still rough idle, so delved into the computer.
Took the ECU apart and saw corrosion around 2 capacitors. Scrubbed the = board and other board connections looked OK. Replaced the caps with = same only 105 deg instead of 85 deg. All symptoms gone at engine cold = start. Fine when hot, except when in neutral idle speed cycles between =
1300 & 1500 rpm with about 1/2-second cycle time. This is only when up = to temp.TS guides say that's likely in the intake air flow -- mass air flow = temp, press or flow sensors, idle speed air sensor, motor, etc.
Already had swapped out the MAS, so next task will be checking the T, P = & flow sensors and connections from that thing. Should be fairly easy = to to this. If no improvement will hit the fuel injectors, timing, etc. =
-- NEXT weekend.
Even if I can't get the miss out, it is already 99% back to running = normally.
Hope this is encouragement to others. Like they say, even room full of = monkeys at typewriters will type out all the great books if given enough = time! LOL!!!
