with that pretense in mind, My car, 1990, #0074 had some similiar
problems as you have described, Upon acceleration, it would sometimes,
fall flat on her face, fart, then, pick right back up, It didn't matter whether hot or cold. and she did it when she wanted.
a few months of this, and, upon arriving in Bowling Green for the gathering a few years ago, I was explaining my problems, to anyone that would listen, standing around my open clam shell. Gordon Killibrew and a host of others, were looking and talking about stuff.
Gordon told me he thought it was the map sensor hose, collapsing upon
acceleration, He said, if the hose was soft, and pliable, that would be one of my problems, he was right, and the next morning, at the Museum,
I went to his tent, and he cut me a piece of new hose, showed How to replace it. He also said he the air cleaner needed to be replaced.
I had dyno'd the car the day before, and after the new map hose and
the air cleaner, it dyno'd and extra 22 hp. Holy mother of pearl, i was suprised, and delighted, and the hesitation was history.
Of course you probably already know, but the map sensor hose, is located right in the back in the middle of your plenum, there is an aluminum bracket, that you take off to get to it. Here's hoping it is something as simple as that.

i have been trying to chase some gremlins in the wifes red car and i read your deal on the map sensor hose ,tryied it and it solved the problem . thankyou , now if i can find that dumb fuse for the vaccume pump? would you know where that little fella is?
