PS: I bought it for $100 late Oct' '05 from a 25yr old neighbor.
Strictly as a second "banger" car to take the extra travel
time off the '01 primary car.
He was asking $300, but for Me, $0. I insisted on the $100.
He told me it needed an complete exhaust, brakes all around,
and front end work. I spent $170 on exhaust from the engine
back, $120 on front pads and a bad rear brake line+cyl, $100
on a new ball joint, and $80 on a pair of tires. Thats $570
for a good running '93 sunbird. My $570 got me 4 good
months and 12k mles. I cant see spending $100 to tow it
home to ponder the puzzle in my driveway, or tow it to
another mechanic to run up a bill.
I'm looking for a list of "Did You Check?" ideas before I
toss the pontiac. Additionally, If I give "O'l Ed" the nudge
in the right direction, He'll solve a riddle and I'll pay him
for a job well done.

If no good ideas come from this, We'll junk it and let "O'l Ed"
hang onto the $100 from the Junkyard.

Thanks,

diagnostic codes?

Since you have positively eliminated everything else, that leaves timing.

Well Ed got it running. Claimed it was spark plug wires. (?!?!)
Ran fine for a few hours, then chugged out again on highway.
After a costly tow, the shop that towed it figured out it happens
as soon as the engine heats up. They are guessing a sensor or
something.  Unwilling to pour any more money into it, so had
it junked. Hated to do it, but it was towed to nowhere near home
    I hate unsolved mysteries
             Thanks to all for the info though.
