My 2002 ford expedition used to sputter at 50 and now it's sputtering at 60? Could it be possible that my spark plugs needs to be changed?
run some good fuel system cleaner thru it ..like>ZMAX..dive it a few day and report back...plugs/wire cant hurt either..
Ok, I'll try that and report back, thanks!
How many miles on the car and when is the last time you had a complete tuneup up, including fuel filter and air filters..
