LS1 swap running like S**t
I got my swap done last month and the car was running awsome. Yesterday morning I finished installing a new Racetronix pump to replace the stock LT1 pump. After which it still ran great. This morning I wash the car (sure it has nothing to do with it) and now it runs like crap. It idles OK but under load from idle to about 2500rpm it breaks up and has no power, above that it's fine again. Since I didn't replace the plugs during the swap I changed the plugs and inspected the wires, which looked fine.
No difference, it still runs like crap. Put my Auto Xray scanner on it and ran a live scan. All sensors have readings and seem to look good. There were no codes in the PCM.
Any Ideas????

Thanks for the responses I didn't need. On a whim I decided to dig around a little. Pulled the two plus off the PCM and water had gotten in them big time. Sprayed out the connectors with contact cleaner and blew it all out. Problem gone!
I guess I'm lucky I didn't fry the PCM. I thought those were mounted under the hood because they were sealed agianst things like that. Time for a cover over the PCM.

that happens so often at my work (dealership). detail blasts the cars with water then they randomly get a misfire... lol gee...
but yeah. that crap happens. If you do something, and something breaks, then you effed something up. crap like that doesnt happen for no reason
