bad stutter at 2000 rpm, only power key on - ZR-1 Net Registry Forums

hello all, newbe here, I am sure this has been covered but this car is driving me crazy.

Runs perfect under normal power, but turn on the power key and idle goes up, and at exactly 2000 rpm's at part or full throtle it sounds like it stutters, bad, clears up at 5500 and pulls hard to 7500.

I have changed the fuel filter and pumps. new plugs. From what I have read in other posts it sounds like bad injectors, but it realy feels like a carb with the choke sticking. I was wondering if the 2nd ports are not opening. I am in Springfield Missouri and need help
