Hey all. I'm daily driving a 84 Pontiac. I have a problem. Whenever I am trying to accelerate onto the highway, my car will bog down so bad it will almost cut off. According to the odd intake pressure sensor, it's not even half throttle, so this doesn't fit the normal quadrabog criteria. I can fling it wide open, and it sputters and throws you back in the seat when it downshifts. The idle is a tad high, and runs a little rough when it sits in drive in traffic, causing a check engine light to come on. I can accelerate after that and the light goes away and then it behaves itself. It's gotten to the point where its hard to start and won't run unless you prime it at least 5 times. I don't think it's the choke, because the secondaries definitely work when its warm, and I can visibly see it open when the engine is hot. I initially suspected a vacuum leak but I can't find any.

What is wrong with my car?
