Vapor Lock

I have searched with no luck. Only after towing have I experienced this. After a long tow when coming to a complete stop the engine starts to lose power, as if it was being restricted until it kicks in again. When this happens the familiar cackle of the engine goes away and it feels like it wants to stahl but doesn't /ubbthreads/images/graemlins/shrug.gif. This is on Drive but if I put it on Park everything seems normal. I tow 8K lbs and on this last trip went for 400 miles roundtrip. I had just replaced the air filter thinking it was a breathing problem but it still did it after the long tow. While talking to a friend that distributes diesel engine parts, he told me it was Vapor Lock. Did not even stop to think of an answer. He says it has to do with the heat and how diesel vapors at certain temperatures causing this to happen. I have never heard of this. Can anyone shed some light on this? /ubbthreads/images/graemlins/confused.gif

I posted this in the upgrades section on the "dead pedal feel" thread going right nowit sounds like the same problem




I think I have the answer!!!! WIRE RUBBING my truck went in for a new trans last week after working flawlessly I had this "dead pedal" feel and the next day the trans wouldnt go into gear it was "dead" they checked it and said cant find i reason it wont work so they put it back in and for the last week it worked great UNTILL I got back from towing and i had this "dead pedal" feel without towing just running down the freeway empty and now the trans is dead again no burnt fluid good operating temps ect but its dead. coincidence I THINK NOT!!! it has to be either a wire or computer problem it is at ford now Ill see what they say in the morning. Just to give a refresher on my "dead pedal" feel the turbo doesnt spool untill around 2800 rpm and the exhuast sounds llike a big block with a huge cam init. I get no check engine light or anything the trans shop said they couldnt pull any trouble codes so it has to be wiring problems right???????? I'm open to any other suggestions
