Help! after cam timing

My 02 Boxster had the scavenge pump on bank 1 sieze and cause the camshafts to jump time. I replaced the pump and gear and re-timed the cams. All looked good putting it back together. It started up fine and sounded fine then the cel came on. I get codes P0300, 301,202, 303. (All misfires on cyl 1-3) I can let it idle and the cel will come on flashing for maybe 15 seconds and it sounds like there is a misfire. The light will go off by itself and the idle smoothes out. This repeats every 15-30 seconds. If I rev up to 2-3000 rpm the light usually comes on and then will go off again by itself after several seconds. I have a Durametric but i’m not sure what to check. The variocam system seems to be working fine on both banks. Anybody have any ideas? Thanks!

You have misfires on bank 1, which may not be related to the work you did other than the coil packs are not fully plugged in.
