I have a 96 chevy silverado with a 5.7 vortec engine. Runs decent at idle and low speeds, but as I apply more gas it acts like its choking out and looses hourse power on hills at any speed. Could this be the throtle position sensor? Ive recently changed the upstream o2 sensors and plugs and distributor cap.
Do you

Scan for codes and check fuel pressure with a gauge 60-66 psi. Auto parts rent it.

Yeah, shortly after posting the question, I read the article on back firing and it made a lot of sence. Thanks for the fuel psi range. :)

One other thing on these if the fp is ok then check rotor in dist it should not move or if it does very little the dist gear wears out and you'll need another distributor.
