its a problem child at the moment here at the shop

i just started a month ago and was put on this car to do phasers and one intake cam

new chains and tensioners. 

the car will run great and is drivable and will perform as it should

for essentially no reason, the vehicle will start to missfire randomly on all cylinders

the codes on the tittle are the codes that are always present even after clearing the DTCs

when i do a code read for the current ignition cycle, the whole DTC list seems to appear

one code.....well 2 that completely throw me off is a P0041 (i think thats the code) that states "heated oxygen sensor signals swapped banks 1 and 2 sensor 2"

and the one that really throws me off U0101 "lost communications with TCM" ......its a manual BTW

it seems to be trowing every single code in the book when i pull up the codes for the current ignition cycle

i havent found a solid answer to this question and it might not even be related to this and might be normal, but the voltage seen bt the Module is 15.2-15.5v at idle and while driving. thats the only think i have really seen as off

i did some research on this and some people say its normal, and others (like myself) think its a bit high

pro demand says it will go up to those levels, but it should come down after a while. also, with the scanner i can see that its being commanded over 80% for the alternator.

anyone else have this issue before? any help is greatly appreciated as i am stumped on this

also the codes i described on the tittle are as follows

P000B Exhaust camshaft position system slow response Bank 1

P0014 Exhaust camshaft position system performance Bank 1

P0024 Exhaust camshaft position system performance Bank 2
