Is my Turbo failing or dirty?
The last 2 mornings have been around -12 degrees(F) as I leave for work. My 2004 was garaged overnight and the heater was plugged in also. It stared up with no problems and I let it idle about 5 minutes before I drove it. As I head down the road everything seems normal for the first couple of miles but then the turbo quits working and the truck is a dog. There is no unusual smoke from the exhaust, no unusual noises from the turbo. I continue to drive about 10 miles on a county road with about 10 stop light/signs until I hit the freeway, then the turbo starts working again like nothings wrong. This is the second consecutive day it acted like this, except today it cut in/out a few times after I hit the freeway. Could there be some moisture causing icing in the turbo? None of my fellow Ford truckers ever heard of this. Also,I just had the EGR replaced but that really shouldn't affect the turbo (?) Tomorrow morning should be around +10F so I hope to find out if it's a cold air related issue. Any thoughts would be appreciated.
