1990 GMC Tracker electrical prob?

Home  \  Repairs & Maintenance  \  1990 GMC Tracker electrical prob?

Hi all, I would appreciate some help on this one. I have a 1990 GMC Tracker and recently washed the engine with a high preasure spray hose. I kept the engine running and experienced no problems. The problem: After I drove home and shut off the engine, it has not run properly since! The motor runs very rough, and (oddly) smooths out if I REMOVE a plug wire! I have checked the distributer, spark plugs etc, all the obviuos stuff. No water anywhere that I can find, and it has been several days anyway since I washed the engine.
Does anyone have ANY suggestions that might help me track this problem down?
Any help will be appreciated.
