N-14 rpm surges at 1000 rpm
I put a used N-14 celect plus into my 98 Pete 379 that I bought from a scrap yard. The engine ran great for the first ten thousand miles then started pushing water. Did the head gaskets and when I picked it from the shop at 1000rpm It will drop to 800 and then recover. Just like you were sitting there jabbing the throttle. I took the truck to Peterbilt and there cummins guy spent a week on it and in the end was told that they had no clue. Tested the engine position sensor they said it was good but I'm thinking I should replace it anyway. I don't know I'm completely frustrated about it. Spent 2000 already trying to chase the problem no one really even knows much about them at the shops anymore.
Is this a good question?
