Please help

Hello. I'm new to this forum so I'm not sure if this is the right place to post my problems. Well, here we go: My 2006 Jeep Commander v8 4.7 L been having issues with starting up, it will act like it wants to start the first few tries until finally it starts. The jeep does run sluggish as well, it will not go over 2500 rpms and the check engine light is on. Thing's I've done according to advice from dealership and local mecahnics have been: replaced camshaft position sensor, replaced crankshaft position sensor, replaced sparkplugs and got a new battery only because it needed one. Oh let's not forget the replacement of a pcm. The dealership suggested it was either pcm or timing chain so i went with the pcm, but 3 days later after pcm was replaced the check engine light came back on. The codes p0344 and p0340 kept popping back up everytime! We took it back to dealership and now its the codes p0016 crankshaft/camshaft timing misalignment-bank 1 sensor 1 and code p0344 camshaft postion sensor intermittent- bank 1 sensor 1. We even checked the fuel pressure too. I keep getting mixed answers of what it could be. Some say yes it is the timing chain and some say its not because I would hear clanking and it would not start. Some forums say it could run with a skipped tooth or two? Idk. Any help as to what direction to go would be greatly appreciated! -JennyJenn

The code P0016 likely just needs the oil pump drive assembly (OPDA) turned just a tad to get the cam sensor back into sync with the crank sensor, the other codes may be caused by the cam sensor misalignment.

You'll probably get more of a response if you post your issue in the section of this forum dedicated to your Commander, it's located here:
