Washed down engine, now have #3 cylinder misfire. Any thought on what got wet?
I just bought a 2003 GS300. Was running great until I sprayed down the dirty engine. I let it set overnight before starting it in case something got wet that shouldn't had time to dry out. Started it and it runs like crap and has a P0303 #3 cylinder misfire code. Any thoughts?

Easy plug replacement. When I got down to the plugs I cleaned the whole area with degreaser and a paintbrush. Then flushed it with water and used a shop vac right away and then blew out the remaining water in the plug wells with compressed air. Worked great and turned out super clean so I didn't have any dirt or anything to fall into the plug holes when I removed them. I had some broken plug wire clips as well. I put new wires on since it has 114,000 miles on it. I sprayed down the throttle body with canned cleaner and a nylon brush while I had it out. Runs like a champ.
