have a 1994 C4 Corvette with an Lt1 engine. It has 65000 miles on it.

I have one minor issue that comes and goes very randomly. It starts with a surging idle. And at low speeds under 60 miles an hour if you lightly step on the throttle *it's kind of like it misses and falls on his face. Step on the throttle *just a little harder to get the RPM's up it takes off like a scared rabbit. When all this is going on it will also be pinging. It doesn't matter if you're running regular or super. Only does it occasionally always seems to be on a hotter day on a long drive.

As you continue driving the ping gets louder and more often and higher RPMs and the *surging at a idle is more .the miss starts going lower down speeds. Never seems act up above 60-65. My gas mileage is pretty consistent between 16 and 20 miles a gallon going back forth to work and normal driving which consists of Freeway in town.20 to 24 on a trip.

No codes in the computer periods everything else seems to be going great. Any help will be greatly appreciated.

Today was the first time acting up when I got my check too plugged in. Throttle position switch voltage stable moving smoothly map sensor voltage all over the place and the four oxygen sensors or also going up and down everything else was stable except for idling was all over the place from 500 to 1800. Any help would be wonderful
thank you
