Default c4 LT1 performance

94 LT1 70,000 mile Transmission doesn't always kick down when I apply heavy throtle, thought it mass air sensor, cleaned and starting working ok, today car had rough idel and hesatated. Seem to correct itself after a few min of driving then it didnt respond with full throttle again. I'm thinking throttle position sensor? Thanks for any help

It wouldnt hurt to adjust it and see how your response changes. It happened to my l98 and all it took was a turn of a screw. But keep track of your turns so you can adjust back if it doesnt help.

^^ The throttle position sensor (TPS) on an LT1 is self-adjusting. There is no screw you can turn.
