I just bought a 2004 Excursion for my wife and "occasionally" it has hesitation at takeoff and acts like the turbo isn't spooling up. It will hesitate and rev up, almost like dead pedal and then will just take off and you can hear the turbo spool up thru exhaust (straight piped). Currently the EGR system is intact however that is coming out this week along with adding an SCT programmer. I have read the could be a dirty maf sensor, dirty turbo, or a dirty EGR Valve. I am hoping it is the latter as it is coming out this week. I bought the truck last monday and it has done it 3 times while putting about 500 miles on it. Any thoughts? I really don't want to drop $1k on a turbo already. Thanks in advance, Jason
