part throttle stumbletown usa
so coming home from the track my car starts acting up.
at part throttle, like keeping pace at highway speed, it just stumbles a lot, all jerky and bleh.
so i get home, adjust the tps, it was .6 at idle instead of 1.
okay that should fix it, right? wrong. still stumbles, if anything worse.
stumbling goes away when im engine braking or giving it more then part throttle.
what could be causing this?

do you still have the stock cats and if so, how many miles are on them. my car did the same thing and that fixed it by just removing them (South Carolina). lol. but i would check that, cleaning the plugs up should be another thing.
