Car runs and idles fine, everything checks out good. At full throtte car is great at 1/4 throttle car is great at mid throttle feels like a miss or flat spot once you push past it is fine. 1991 L98 auto.
I venture to say that your throttle positioning switch is probably going bad... (TPS) they are like a variable resistor and since most of the motion is in the mid part of the switch it's probably getting worn out...
If you disconnect it and put an Ohm meter across the terminala and move your throttle the readings should be very smooth, it is seems erratic then that is the culprit...
