Ok, this may be a dumb question, but this is the first Powerstroke I've owned..
When you decelerate (coast) to a stop sign in the country, it sounds like the engine is actually shutting down part of the time and only firing occasionally. It isnt running bad, and it sound like it is by design..
I was wondering, 1) is that what its doing? The truck has an aftermarker muffler, tailpipe, turbo downpipe, and chip, so you can generally hear the engine pretty well
And 2) if it is doing that, is that a Powerstroke design, or being done by the aftermarket chip... We have no idea yet what chip is in it.. We were told the former (original owner, we're second owners) put a chip in, but no one was sure which one.. If it is doing it, for which ever reason, it definetly helps the deceleration with the horse trailer... This has no exhaust brake, but it controls the decel better than any other diesel I have driven without an ex brake.
And a quick 3)... where is the computer in the '97 CC F350.. I'd like to take a look and see if I can tell which chip is in it, but I dont know where it is on this model.
