So a few weeks ago my CEL came on while driving and started idling very rough with limited power to the throttle. Ran the ecu, turns out P0341- Bank 1, P0300 Random/multiple misfires, P0301 Cylinder 1, P0303 Cylinder 3. I did some reading on a few forums and all signs pointed to camshaft position sensors. So i changed both of them AND changed all 8 spark plugs. It seems like the rough idle is fixed. While at IDLE and in drive the CEL will turn on and flash. When driving, the CEL stays off until RPMS drop to idle.

My next thought was the crankshaft position sensor as the next replacement. Worst case scenario is the tensioner is damaged and the chain/and or tensioner needs to be replaced.

Does anyone have any ideas as to what the issue is here? any help is appreciated
