No acceleration and high temperature when its hot outside. 200 1990

I'm going to agree with everyone here as far as checking the catalytic convertor for low or no flow, remember a muffler with broken baffles will also create an exhaust restriction.

The first thing I'm gonna ask you to do is start the car, and pull the fuse for the pre-pump and see if it makes any difference in a) how the car runs, and b) the noise level of the hum of the main pump.

Hot weather really does make a weak pre-pump show it's ass.

Question number two, when you accelerate, I mean really accelerate put the pedal to the floor, does your transmission downshift well to allow you to speed up, or does it kinda down shift once and blahhhhhh itself a little faster? A detent cable can look fine up top at the throttle linkage, and still be broken inside the tranny.

Just a few questions...

Chris
