Coil pack was tested by using one of the old spark plug cables and a spark plug. I disconnected the plug cable at the coil pack for cylinder #2. I then connected a previously removed spark plug into a previously removed spark plug cable. I connected my "test" cable to the #2 position on the...

After disconnecting the battery for about 10 minutes and then driving the jeep around a bit further. I returned to Advance Auto....the misfire code P0302 on cyl. 2 had returned. Along with the secondary O2 sensor. Changing the thermostat fixed the fault code for it. I think you were correct...

Just had codes read again after the CEL light came back on. Cylinder 2 mis-fire is back, and the secondary O2 sensor too rich is still there. I assume the O2 code is due to the mis-fire. Any idea on how to check the coil pack? Whats the probability of it being an injector or cylinder? Jeep...

Just replaced the thermostat. No change with the miss/rough idle and acceleration. So as of right now the following has occurred: - replaced spark plug cables (this cleared the mis-fire code) - replaced spark plugs (plugs that were removed appeared to be ok though) - change out secondary O2...

Never mind I found it. I will update after replacing.

I had the codes rechecked. This time the code was the MAS/MAF sensor dirty, O2 secondary running rich (or something like that) and the thermostat (don't recall what the error said). I just replaced the Bosch O2 sensor with an NTK brand. Cleaned the MAS/MAF sensor. Started the jeep and...

Thanks for the responses....just to be clear the glowing catalytic converter I was referring to occurred about 3 days ago. That evening I went to Oreily's and ran codes. Codes came back as mis-fire on cyl. 2 and the O2 sensor at converter slow to respond. I then found a bad spark plug cable...

Bosch was the only one they had. I also ran a bottle of fuel system cleaner with a full tank of gas and it appears that some progress has been made. I was thinking that a fuel injector was sticking or possibly leaking. Figured I would try it before possibly working at that. Still hesitating...

I have a 2006 Wrangler and have been experiencing some stalling issue when decelerating. A few days ago the check engine light came on. I checked the diagnostic codes and codes said a mis-fire on cylinder 2 and bad O2 sensor at catalytic converter. The converter was also getting hot and the...
