p0196 and p0603 dtc

[sgt dave]

i have been trying to figure out why my other truck has an intermittent loss of power issue. truck starts and runs great, but sometimes it will lose power and wont accelerate. truck is a 96 f350 cclb 4x4 with 192,xxx miles.
i did a buzz test today and all injectors passed then i did a cylinder contribution test and got p0196. then i checked for other dtc's and got p0603. can someone elaborate on these codes please and would they cause an interrmittent loss of power situation with the truck. thanks

mods on truck are t500 hpop, 6637, ccv, banks intercooler and ottomind chip, ats transmission, 3" dp to 4" exhaust

P0196 Engine Oil Temperature Sensor Range/Performance, P0603 Internal Control Module Keep Alive Memory (KAM) Error. I don't see how the Kam error would effect performance, but it is possible that performance may be effected if the wrong oil temp is being sent to the PCM. Are you sure that all your connections going to the injectors are good? Maybe move the injector harnesses a little while doing the tests.

Thanks for the reply. I'll check the injector harness and valve cover gaskets after work.
