WP - thanks for setting me straight. Thanks to the great members, we learn stuff almost everyday on this board.

Good luck. Please keep us posted as to what you find.

Mine does surge a bit, but only at very low speeds, or if I'm driving on very hilly whoop-de-do type roads. In both cases, I suspect it's the turbo kicking in rather than the cruise not controlling well enough; it can only react gradually, whether that means adding more pedal or backing off. On open roads at speeds above about 55, there is no surge whatsoever...it stays absolutely locked in at the setpoint. For hours and hours and hours if I'm on I-5...
Resuming cruise after braking is fine too, it gradually accelerates to the setpoint - unless I'm using it in one of those very slow or very hilly areas I mentioned.

Jack, you mentioned your cruise surges a little at lower speeds. Does your truck do it without the cruise at the same speeds? Mine has a slight surge at "in town" speeds. It is the most noticable in the lower gears crawling along between 1,000-1,500 rpms with a light foot on the throttle. I have been told it is air in the fuel being supplied to the injectors. The factory fittings in the tank and pre-pump lines are letting air in.

I have the V10 with auto and my cruise also surges...I find that it does this most going down long hills. Took it in to the dealer and of course since there aren't any long hills around the dealer they couldn't replicate it so they couldn't do anything about it...sigh.

I recently went to VA. to bring niece/apt. furniture and unreliable car back home from college, and towed U-Haul car trailer back to CT. VA has higher speed limits than CT. and I got reaquainted with surge on way there. It was windy, and the surge started makin' me nuts. I tried cruise with overdrive on & off but it didn't change it -still had cyclic increase in speed then drop back down, over and over..... Had to disengage cruise and restart it mulitple times. From watching the tach, it seemed that it happens when torque converter locks or unlocks. I didn't want to go any slower (10 hour trip), so I turned the cruise off and finished trip with manual go-pedal instead. Never have noticed surging without cruise on. Forgot about it again 'til I saw this thread.
Strange thing on this trip, engine never surged on return leg towing trailer/car w/ 1/2 ton of stuff in bed, and three passengers. Truck was perfectly happy at 70 mph with a load.
Seems like it's a design feature to me - V10 tellin' us either work me or go faster! ;-)

It sounds like you and some of the other folks are seeing their torque converters come out of lockup when they really shouldn't be. Once I get fast enough to be fully into OD (TQ Lockup) it stays locked until I hit the brakes or find a really steep hill to climb. The faster I drive, the less likely it is for the TQ to come out of lockup. At 65 mph, I routinely pull 7% grades in OD with the TQ locked. I'm sure it would pull steeper ones than that and still stay locked, but can't recall the last time I drove over one.

Can you tell me how you get that much better mileage? You must have a secret.
jerry
Watkins, I have a 350 version of your truck. The only way I can get that kind of mileage is if I set the cruise at 50 or 55 and drive on a flat road - preferably with a slight downgrade and/or a nice tailwind. If I'm at 65+ it's more like 17-18, and that's running empty with a hard tonneau cover. Is that real mileage you're quoting, or a number from the computer? Short term or long term average?
JT
You can also put the engine under load and watch to see if it "torques up" very much. That's easier to do with an automatic; you just put it in gear and keep one foot on the brake while you feed it a little gas with the other. With a stick, you could probably still do it by setting the parking brake and maybe placing some blocks in front of the tires. You could then (with the hood open) peek under the hood while you slip the clutch, or have someone else do it for you while you watch the engine for movement - be sure to stand to one side, and not in front... ;-) If it moves more that a half-inch or so when it loads, I'd be asking the Ford guys if there's something wrong.
If I remember right, yours is only a couple of years old, so it's pretty unlikely that the mounts are shot unless you've been awfully rough with it, or have been really unlucky recently.
JT
From replies I've gotten, I was beginning think that the surge is different between gassers/diesels, and Autos vs.manual trannies. Don't begin to know how cruise control works on a diesel, so I can't even a hazard a guess as to what if any common denominator there is between them. Maybe some programmer goofed in his code when they designed the cruise software. :-)
Many thanks!
Just my $.02 worth.
Some have found heat shield weld broke, and fixed with muffler clamp.
PS - Anyone know where I can get some info on the next generation F150's?

Lately, I've been wondering if it might be the front driveshaft, since it almost always occurs just AFTER I've been in reverse (and turning).
I have an '01 F350 CC, 4x4. Had problems from day one with loose cab mounts ( which were properly tightened after a couple of attempts). Also had popping/creak noise from front springs on slow speed bumps and also noticed it like JDTopper said on off-camber turns. Dealer put on spring tip isolators at 15K service and it's been quiet for the past six weeks. I think some folks have upgraded front end to "x-springs" from F450s to help level the truck better and in an attempt to get rid of the noise.
Two weekends ago we drove from Gardnerville, Nevada (near Carson City and Lake Tahoe) down to Yosemite National Forest. Drove around the forest and into Medesto then back home over Ebbetts Pass. A scary road. Not trailer friendly. No middle line and just wide enough for two vehicles. Just had camping stuff in the back and no trailer.
I did the calculations for my trip and I was expecting something around 18 MPG but it was an amazing 24.6 MPG! I've never done so well. That's almost as good as my '97 Grand Prix.
I am honestly jealous. I just filled up with 36 gals of gas at $1.51. Travelled 470 miles on relatively flat roads and got ~13 mpg with V10, 4x4, CC,LB. I suppose I could learn to tolerate diesel exhaust.
The cheapest diesel fuel I can find around here (but still a well used place) is $1.43. It's usually $1.39. Gas prices and mileage were key factors in the purchase. Even though I knew I wouldn't use it to it's full potential most of the time.

package. I noticed it sitting slightly lower on
the drivers side. After taking some measurements
from the wheelwell to the ground, sure enough. The
drivers side is 3/4" lower. Anyone else notice
this?? If so, can it be levelled???
Went there and they are now www.thedieselstop.com.
Did a search on "drivers side lean" and got no hits at all on this new site. Oh well.
