NEED DIAGNOSTIC HELP!

The engine was running rough. I hooked up with a mechanic for computer diagnostic. codes that came back were, P1271#1 cyl high/low open, P0603 internal module KAM error, P1316 IDM codes.

Hoping this is just a sensor problem. Any ideas?

Check your UVCH. This is the Under Valve Cover Harnesses, they can come loose (there is a mod) and it can also burn the pins, so check for burned pins as well.

lol i dont know, i can never remember. i think its passenger side front cylinder.

either way the UVCH's are in the valley side, riight under the valve cover. i think on the SD its one connector each side... not 100% sure.

Do you happen to have a chip in it? Usually the KAM code is thrown from the "flip chips"

I agree on checking the UCVH, may be time for the $.50 mod:

P0603 P0605 can both be caused by a chip or unplugging the batteries.

how much of a task is it to remove the valve cover on the passenger side? I'm a shade tree mechanic and I was looking at it and it seems to me that's a pretty big job. lots of stuff in the way. any advice? I would like to attempt this myself and save a couple of dollars but I don't want to make it worse either.
