86 with no power
1986 4+3 Corvette: symptoms...the car is sluggish, it seems to be idling rough, at around 6-7 rpms.That is it seems like it is missing. When I ease on the gas, the car seems to perform fine, except when the car is in overdrive....then it seems to be chug. Also, when I "get on it" the car seems sluggish, like something is holding it back.
I changed out the fuel filter and that seems to not have done anything. I have inspected the distributer cap and button. The cap seems to have some carbon buildup on the contacts, but other than that nothing. Besides, it is only 2 years old. I have changed out all the plug wires and spark plugs. My next step is to run some sea foam through the engine and clean out the throttle housing.
Other than this, I cannot think of anything else except the catalytic converter. By the way, there are no vacuum leaks. ANyone with any thoughts?

Any muffler shop can run a back pressure test on your cats. The cost is negligible.
Before spending any money on parts and tune-ups that would be the smart place to start.
Next is codes. Fuel mileage. Etc.
