Last week I bought the injector cleaner and dumped it in. Seemed to run better after that.Then I got the plugs in on Friday and put them in this morning. When I pulled the old plugs out, #1 and #4 had white mineral type deposits on the top side as well as condensation to indicate water got into the area on the top side of the plugs.After replacing them all I drove around for about a half hour and everything seems to run fine so I think the issue is resolved.I have a theory about what had happened though. The 2 hex screws that hold the injen spark plug cover uses the holes for the bolts that hold down coil packs 1 & 4, and these were a little loose when I was removing the cover.I think over time the screws worked their way loose so the coilpacks weren't as tight as they normally should be and then when I poured water over it to wash, some got in.
