Number 4 plug getting wet any ideas?
Recently my car started missing. Checked it out and found number 4 plug to be wet with fuel. Cleaned plug swapped for another from cylinder 4, re started and run fine then after a few mins miss fire again, same problem number 4 wet. Done compression check and all ok, good spark too and injectors are only 800 miles old. It's run perfect for 800 miles denso plugs. Any ideas before I pull it apart again?
