- 2003 Explorer Limited 4x4
Just picked up a 2003 explorer 4.6 4x4. It sometimes studders surges and bumps when accelerating hard or up a hill. Other than that shifts smooth and runs smooth. No service engine lights yet.
What are your thoughts? Random misfire or tranny issue?
When it messes up, it starts off as a surge and then a soft stumble then it goes to a hard bump bump bump until you let off the gas then it may do it again a few more times if you get into the gas too much. By then you are up to 55 60mph it will do it in OD and 4th if at 55+mph if you get into it or hit a long hill. Other times I've tried to make it do it and it is shifts and runs flawless.
