Well, it all began with the initial spring start. Ran very rough, idle jumped up and down, engine stalled.
I cleaned a few electrical connections, cleaned throttle body, seemed OK.
Problem returned, I replaced plugs and wires, seemed OK.
Problem returned, I replaced fuel filter, ignition module, air filter and serpentine belt, checked injectors, seemed OK.
Problem returned, checked codes, and per codes, checked for air leaks, replaced Throttle Position Sensor (TPS), Idle Air Controller (IAC) and Mass Air Pressure Sensor (MAP), did not correct problem.
Wits end, at this point I am out about $680.00 in parts.

Take to shop. Local shop, small but very busy and willing to work on older vehicles. They checked fuel pressure and timing and some other things, couldn't resolve. Called in electronic specialist, no quick answer, so shipped it to specialists shop. Specialist tried to test drive, could not get it into any gear ( 6spd standard). Back to 1st shop. 1st shop replaces clutch master cylinder and clutch slave cylinder, still no gears, replace clutch plate (flywheel was OK) and starter. Back to electronic shop, has it for 2 weeks, reports no running problems, I go to pick it up. Starts , idles, tranny works. I remain baffled, I do not know how replacing a bunch of mechanical things can correct a mysterious rough running problem. Also baffled at why it took 6 weeks in the shops.

The 1st shop didn't charge me for the slave and master cylinders as those were not the problem, also didn't charge for the new starter. The electronic specialist charged nothing as found nothing. I paid out $2800 to the 1st shop.

So here I am out about $3400 and unsure how it all got fixed and it crossed my mind "maybe its time to sell?" I took it out for a good run and on the Bass Lake sideroad, a tree covered, serpentine stretch not far from home. The fall colours were beautiful, the gears shifted right, it cornered like a corvette and... it put a great big grin on my face.... So..... Nope, gotta keep it!
