Ok. So I picked up a project. 91 SE. When I got it the wiring was laid but not all connected. Hoses weren't connected car didn't run. Started to play with it. Got it to idle but once I press the gas it will almost die or it will die. Played with the timing n for the most part is on point. Dizzy kicked my ass for a while n wouldn't start. Now it starts idles up a lil to about 800 than sslowly drops down. Get to the point where it sputters n pops at a low rough idle then dies. New cap n roter. Any ideas or test points please.

Do you have any CEL?

No but it's hard to say cuz the car won't run for longer than around 10 mins. It starts gettin real jump/lope on the idle than starts to choke its self out.

If the maf was to blame, I think you'd have a code
