MISFIRE # 6

2001 Cadillac Catera

Engine Mechanical problem
2001 Cadillac Catera 6 cyl Two Wheel Drive Automatic 104000 miles

On my catera #6 cyl. Misfires at idle, but when I punch it clears out. When I pull the plug it is wet. I changed the coil packs from one side to the other same thing wet plug. So what do you think the problem is and how to fix. Thanks. Bob.

Check the compression and injector for no.6

Plug getting wet might not be firing or the injector is leaking

Engine misfiring can be caused by worn or fouled spark plugs, a weak spark (weak coil, bad spark plug wire), loss of compression, vacuum leaks, anything that causes an unusually lean fuel mixture (lean misfire), an EGR valve that is stuck open, dirty fuel injectors, low fuel pressure, or even bad fuel.
