I recently noticed some rough idle at times with my Journey, then into a short drive at 50mph the engine started missing seriously and the check engine was light flashing on/off. I limped home and the OBD scan showed cylinders 1,3 & 5 misfires and crankshaft to CAM misalignment. HELP!!!!

 

How many miles on it? Could be any number of things, stretched chains, failing sensor, etc.

 

Last tune up?

 

147K miles, tune up at 100k

 

You need to get it to a shop.

 

I had the same issue but to cylinders 3 and 4. It was the coil packs that needs to be replaced so I had all 6 replaced. Car runs smooth again

 

To make a long story shorter, I replaced my coils finding a burnt one in the process and have had no problems since. The 1st shop I took it to said I needed a new engine based only on the OBD scan that the crankshaft & camshaft were misaligned, but the engine was running fine with no engine noise……

Thanks for your reply!

 

I wouldn't rule out plugs. My Durango got drivers side coil packs (one failed, replaced all 3) and all 6 plugs at 85-90k. Just this last winter has random misfire again at 145k, replaced other 3 coils since they hadn't been. Fixed it for a week maybe, issue returned. (Had previously serviced rockers due to roller failure, worried I messed up the cams). Decided to pull plugs, my plugs with 50k on them had already burned out to .085"+, new plugs and good to go, hopefully got better ones this time
