CHEVROLET SILVERADO CHOKE PROBLEM

1994 Chevrolet Silverado • 145,000 miles

I have a 1994 Chevy Silverado 1500 4WD with a 5.7 eng. And a 5 speed trans. It starts and idles fine and runs fine under throttle out on the highway. The problem is just off idle, like in first gear pulling out a driveway with very little throttle or out on the highway at cruising speed in high gear with very little throttle it cuts out and bucks and acts like it is loading up like running with the choke on or something. I have replaced the plugs & wires and the dist. Cap & rotor. Any idea what would cause this?

Check to see if the gasket under throttle body is blown, spray some choke cleaner around it you'll know pretty quick if it its. Check fuel pressure and scan for codes.
