Ok so i put some acid and degreaser on my engine and power washed it off today. No big deal I do it all day during work, but for some reason the engine wont rev past 2.000 rpm! I havent driven my z for about a month untill today. When I got in my car and started to drive I noticed the speedo was starting to bounce and then it got worse when it shot up to 65 and wouldnt drop below 40 untill i was stoped when it droped to 25.... and when I push on the gague cluster it jumps another 5mph, but it still drove just great. But after I washed it it cuts out at 2 and drops down then stops at 2 again and will continue to do this when I hold the peddle down. I checked all the plugs and vacume lines I could see and nothing.
so If anyone has any clue what is wrong please post, thanks in advance.

you got water in your throttle Posistion Sensor (TPS) thats the lil black electrical plug next to your throttle body.. take off the electrical connector and blow it out with air.. .. that should solve your problem..... always remember to cover your distriuter and most of your electical componets when you wash your engine....
