Random misfire codes

Could a bad or failing cam position sensor cause multiple different cylinder misfires? I also get a multiple misfire on start up once in a while. It seems like the number 6 cylinder is the most common code I throw. The coils have all been switched around so unless different coils intermittently go bad on that cylinder I'm ruling out my coils. The plug will be wet with fuel when it acts up sometimes it will go 10 miles sometimes it will go 50 feet before I have a problem. I also get a multiple misfire on start up code once in a while. The engine is new with 270 cams Trick Flow heads and a 5.1 stroker block. Any ideas?

If its wet with fuel maybe you have a bad injector ring leaking at pressure. Or the could possibley be a leaking injector flooding on cyl 6

No no no the plug is wet because its misfiring ... Nothing to do with injectors anyways who installed the cams? Who put timing chains in time ? Computer is tuned to run with that motor ? If the coil and plug are good on 6 and it has good compression it's likely the PCM.

My mechanic friend did the cams and chain. The cam gears were set to the factory setting and I saw the timing marks all lined up. The car isn't tuned for the new engine could that be the whole problem?
