my car's experiencing something i'm not sure how to approach. it starts and idles normally. on driving it down the street, anything more than 15% throttle, it chokes and doesn't have any power to accelerate. it's been quite a while since the car's been driven hard. I spun rod bearing last summer and that's been replaced, crank drilled & polished, external oil cooler installed.

so what are the likelies? FPR/FPD? AFM? DME?

car is a 83.

Did this start immediately after the engine was put back together?

i haven't tried to drive it hard since last year. put the engine back together last fall but couldn't get oil pressure back. towed it to shop and i just picked it up a 2 weeks ago. i drove it back highway 130miles but that was just normal cruising acceleration

check fuel pressure...maybe a clogged fuel filter.

check the vacuum line that is under the rubber piece that goes from the air filter to the throttle. same thing was happening to me i thought i had water in my gas or my spark plug wires were shot but it turned out it was just a simple vacuum line had come off

hmm yea i guess fuel filter might be possibility. enuff flow under low power but at high.

my vacuum system's been chopped to barebone and i verified they're still all connected. so not that
