cold weather startup???
first winter with my 02 psd dually, and had a question for the guru's
at very cold weather startup...she starts like a champ, but soon after the idle bumps up to 1100 rpm and it sounds like the exhaust is restricted or bypassed. If I touch the fuel peddle, it kicks right back to normal...I assume it is a warm up choke.
The main info I would like to know, is when I leave after 3-4 mins of warmup, and at regular almost idle acceleration it sounds like the truck bypasses the turbo as I hear a fweshing (air blowing) sound at the passanger side, If I push a little harder on the peddle it goes away, and once it is up to regular operating temperature, all returns to normal.
is this a feature powerstrokes have so that at cold temperatures the turbo will not compress too much to damage the engine?
thanks to all info
