need help code 21 but tps is new and set right

Ok i recently experienced a lot of problems with my camaro which is a 5speed v6 multiport FI

it raned real ahrd on my way to work and was forced to hit huge puddles.

i stalled out at a stop sign and took me 10mins before I could get going. im guessing something like the distribuotr got wet. but no engine codes.

but the next day real sunny and hot goign to work again I got a code 22. the next day i replaced the TPS sensor and disconnected the battery to clear the code. i also set it to .54v with just ignition on and it reached aroudn 4.5 v at WOT.

i drove around for about 10mins and car ran great. I had to go out maybe 6hrs later and its muggy and slightly drissle rain outside. and i barely make it down the road and i get engien code 21 with the car shaking and bucking hard back n forth.


what the heck? the tps is new and set properly.

any ideas?????
