Default Cutting out!

I'm getting a brief hesitation when I press the gas pedal about 1/4 the way down. If I let up off it or press down futher it catches. I also get a slight cut-out as if im loosing spark or have a dead spot in my fuel supply when im traveling at about 40-45 mph.
Thanks!

I'd look into putting a fuel pressure gauge on the fuel rail and take some pressure readings with the vacuum line on & off the fuel pressure regulator and check the bleed down times once the key is off to see is the system is holding pressure @ the rails.

Help us out and post the year of your vette and any other issues that may be related/wrong with the car.

I have the same issue happening. It's going into the shop tomorrow. I really don't want to just throw parts at the problem. I'll post the solution to my issue as soon as I find out.

In my case (94 LT1) it was a faulty o2 sensor.

a4 or stick?

A TV cable that is not adjusted properly on a a4, will give you that feeling.
