My 94 6.5TD engine rpm started racing way up for short periods just recently as I am driving - I have to slam on the brakes... It sometimes stalls afterwards but that is no the usual case.
I have heard two possibilites 1. air leaks in to fuel system and 2. oil from turbo leaking into air intake (acting like additional fuel). I had some leaking on my filter hoses and seals but have repaired that by replacing hose connections and re-done the seals now that all appears to be ok. I am going to place a clear plastic hose on next to see if there is air in the fuel. Re the turbo issue, I don't know how check if oil is getting in via the turbo but I don't seem to be losing oil level on the dipstick.
I was advised that this is a sign of the IP going also. I replace the IP about 3.5 years ago and the PMD has died since and I am back to the Sol-D which I keep on as a spare (which has saved my bacon twice now). The fuel injector company said this is a sign of the metering system going...
I have checked my grounds, disconnected and reconnected my Throttle Position pedal resistor unit, I haven't done all the connections on the main computer yet but that will be next.
I am getting a DC35 occassionally (I was getting 36's a while ago).
Any thoughts what else I might check or do before replacing the IP?
Thanks,
