2006 Ford F150 Slipping on low RPM Sign In

I have a 2006 Ford f-150 5.4 4X4 90,000 miles. When driving down the road and pulling lower RPM's (liking pulling a hill) it seems to jump alittle. I have cked the fluid and filled it up, and it still seems to do it. If I push the button and take it off of over driver and keep it running higher rpm's it seems to be ok. Any ideas?????


Thanks,
Kevin

Could be a misfire. Might not be missing enough to cause the computer to trip a code. You'll have to take it to a shop that can access mode $06 to look at misfire information.

If I was in your place, I would check out the spark plugs.
They should be tan or grayish color.
Since you think it's misfiring, misfiring are caused by bad spark plugs (visual inspect), wires (check with DMM Should be 10 thousand ohm per foot, or visually inspect for cracks), and coils (can be swapped out with a good coil or checked with a DMM) .

It's possible it could be in the transmission, but you should monitor for misfires first before condemning the transmission.

There are no spark plug wires on this one. It's coil over plug. You don't want to pull plugs on this motor unless you plan on replacing them. The plugs on these motors are notorious for breaking while taking them out. If one breaks, you need to buy a special tool to get them out. If you can't get them out with the special tool, you have to remove the cylinder head to get them out. I just tuned up one this morning and had to extract three plugs.

If it does show misfire counts, usually its a coil breaking down.

May just be the trans shifting in and out of o/d. Not sure about later models but earlier E40D transmissions had an issue with early application of o/d. They would shift into o/d almost immediately after third gear and pulling hills they would often go back and forth. An aftermarket delay box that plugged into trans wires largely corrected this problem. If no engine issue found, I would look at trans. I'd leave o/d off when climbing hills anyway.

Good thought. Trannies were never a specialty of mine but heavily studied back in the Stone Age! I own and have driven tons of Fords (much older than this) and no issues for the silly little driving I do but fill it with people or a load AND add hills at around 35ish it sure can get confused in and out of OD but just put it in plain "D" and all is fine.

Nothing wrong with any of the transmissions just under certain loads and conditions they are at that confused point. If this is the case and said up top taking it out of OD solves it that may be it. Isn't that why they give you a choice to?
