You have a fairly complete list there, amybe that's why no one has ventured to guess.

I will say this; there are shops who have not done the timing they have contracted to do, or they have done it wrong.

Sometimes even a new cap can have a hairline crack in it, undectectable to the naked eye.

Some people have changed out thier WUR and AAR to no good effect - could be a dead end, something to research.

I guess you know about the spraying starting fluid around your airbox and on hose lines to search for leaks. You must have a firee extinguisher at your side, "search" this topic up to find out why.

What year is this?

Do you still have points?

How much play is in your distriubtor?

My car threatens to buck at low speed, low rpm.............nothing as bad as when the timing was off. She starts right up and stays running now, used to stall when cold before and buck like a horse with a stone in it's shoe.

I found that slightly increasing my spark plug gap from published numbers helped, I was getting little back fires before and running rich at idle.

Without fixing the root cause you are going to put out of wack other related systems to make up for it. Not the best way, start with one topic and work your way though.

Good luck.
