truck makes noise like a jet engine trying to spool up. it doesn't loose rpms but will slow down at higher rpm. does not seem to do this on level sufrace only when pulling any grade. I tow a 5th wheel.
The vanes on my turbo failed 3 different times. My friend who works at Garrett told me the first time it is due to the small diameter oil return line, Ford laugh at me. Then at 65,000 they told me of their great fix, I laughed after I had them bring my service records and my documented comment.
Starts fine, idles fine give it gas and it sound as if it's missing specially on a hill. Once you get turbo to about 20 lbs. picks up and goes replaced fuel filters and air filter. Air filter helped problem for about a week. Now it's back to chugging to work. Good thing I only work 2miles from home.
