3.7 misfire problem strikes again

[LibbyLife720]

I flushed my heater core at home(probably a bad idea but a guy needs heat) and it got some of the coil packs wet on my 2003 Jeep Liberty. It ran fine for a couple hours but then it started to misfire. If I attempted to go above 2500 or so rpm the engine would cut out until I released the accelerator. Read codes that it was a miss in cylinders 4, 5, and 6. Replaced coil packs on cylinders 5 and 6 because the inner spring was visibly broken. Reset codes and its reading a misfire in cylinder 5 now. Ran fine but after reaching operating temp the CEL came back on and it loses power again. Help.

I would also like to mention that the last time I had my heater core flushed professionally the same symptoms came up and all they did to fix it was blow off the coil pack to dry it out.

Need to pull both the coil packs and the plugs to get them completely dry. Of course if you ran it some then shut it off there maybe enough heat to dry everything after a while
