HELP !!! Car is running like crap

[C. C. Stang]

O. K. I changed my throttle body this after noon. I went from a 58mm ( 86' GT ) to a motorsport 65mm. I took it for a test drive and it ran fine. When I got back I wash the car. I also washed the engine. I took it out after that and when I gave it gas it sounded like crap. It sounds like it's misfiring and really chopy. I wasn't far from my house when it died. I pushed it into a store lot, but it wouldn't start. I did get it home and it is now back in my garage. It seems to misfire and run rough after 2300 rpm's or so. Is it the throttle body or is it from the water ? Please HELP.

take off your distributor cap and look if there is water in there, that could cuase it

Check for shorts by the coil too. Even if you don't see water in the cap spray some WD40 in it to displace moisture, or let it dry out.

You nailed it. I took the cap off and dried it out and the car ran fine after that. Sorry it took me so long to reply, but my computers been down. Thanks again.
