so you have no power warm, it runs fine on initial start up?? Also, has there been any check engine lights or any other issues to note besides the lack of power?? do you have gauges and whats the boost look like if you do??

[hayder1]

Hi Mark, It starts fine, then once your on the highway she seems to rev up 3000 goes through all the gears and tops out at 60-65 mpr, Then I shut it down restart and things are fine, I had the vgt actuator and the egr valve replaced, the check engine light was going off and on at different times then off after the dealer fix, Other then that it seems fine, Thanks again Darcy

Mark, I forgot about the boost, I have no gauges yet but ford is saying the boost on there road test was 25.5 psi? I hope this helps, Darcy

almost sounds computer related....no other symptoms to speak of??

Mark, today I fired it up, there was grey/black smoke 3-5 seconds, then it cleared and ran great! Other than that it drives and sounds fine, Thanks Darcy

my truck bucks and hicups around 45 to 50 mph has anyone else had this problem?

[hayder1]

No I havn't seen that yet, I have the truck booked in for a reprogram next week, I'll post the results, I'll ask the dealer if they heard of the bucking problem, Darcy

OK Just got the truck back from the dealer and they say there is a temp sensor that only allows the turbo to produce a certain amount of boost to save the motor from damage due to cold temp 's on start up, Sounds good, but the truck was warm to begin with so I think the sensor may be failing. Any comment? Thanks Darcy
