6.0 multiple codes

[StrokedFx4]

Sorry, this is kinda long...Had an oil leak and some random erratic running but not too bad. Checked codes, P2285 ICp sensor. I changed the sensor and replaced stock breather assembly. Hard to start after this but when it finally cranked it chugged and didn't want to idle smooth. after about three minutes it plained out and idled much better. I decided to take a test drive, after about three or four miles it made a strange noise and started chugging again, when I got home I put my scan tool on it and it threw a #5 cyl injector low curcuit. I thought it might be a fluke so I noted the code and then erased it to see if it would throw it again. when I erased the code it started right up and ran fine. I drove it again, this time it threw up # four cyl cont/ balance fault, again noted then erased. started fine and ran great again...since then it has thrown up crank position, cam position and #3,#4,#2 contribution/ balance fault codes. did replacing this sensor cause a glitch or did I have three injectors go nuts??! Please Help!!

Im not going to be much help but how old are your batteries? I know I have read where low batteries have wreaked havoc on different electrical items. If you test them they have to be tested seperately good luck

One of them is about three years old, the other about three months. I hate taking it to the dealership but I guess I'm going to have to.

Turns out that a low voltage output on my alternator got my FICM, new half shell, a friend that works at the dealership...$300 and I am a happy camper, she is purrin' like a kitten!!
