01 Cummins 5.9

While driving down the road the rpms will jump 200-500 most the time with the ac on sometimes w/o! Done some research and found stuff about battery cables being bad so replaced the positive cables and hooked up 2 grounds I found that had broken! Thought I had fixed my problem but 2day it did it again the only code its showing is P1492 battery temp sensor so changed it but code still there so I'm stumped!!!
