Vibration / hesitation / surging at low rpms
Can anyone help? I have a 2000 V10 X, and all of sudden I am getting a good vibration at low rpms (1000-2000 is the worst), and any gear, during Acceleration. Under hard acceleration, it appears to go away, and it gets better above 3000 rpm, but I can still feel it. It also will do it in 4x2 or 4x4. It happened while the truck was sitting for a week (on vacation). If I coast (no gas), there is no vibration. It feels like there is a hesitation going on as well, causing the vibration. I do know it is NOT the tires. Any help would be appreciated. Thanks.

Just recently I replaced all 8 (I have a V8 Excursion) of the COP's, it was about $400 total for all 8.

So, it ended up being some coils (2 of them) - took it somewhere to have them replaced. What makes these go bad? Are they easy to change - any how-tos? As only 2 have been replaced, I still have 8 more opportunities. Thanks.

91k on the odometer. As it cost enough for 2, I don't want to do the others unless I can do it myself - do you know of any DIY writeups?

When I was moving from FL to TN after filling up at a chevron station a few miles down the road the more I press the pedal the slower it will go and it wouldn't even go above 40 on I75, I call the dealer on the road and they said it sounded like the tranny, I then called my friend and he said that that happened to him once and he added some additives to the gas and it was ok, I did that and it started driving better. The next morning and for a few weeks after that is was bucking, black smoke, and hesistation then I read here about the COP issues, so I was gonna replace them then all the weirdness stopped. Since it stopped it didn't happen again. All because of a tank full of bad gas.
