glad you found it...
btw a lot of the superduty trucks are made in louisville, KY (huge plant there) and from what I've been told (& seen) they make and park in the lot by series(250, 350, etc), body, color, & drive train. so when they need a red F250 4x4 cc to load on the hauler for seattle/denver/bismark..... you get the picture... who's to say

Has anyone experienced a "hesitation" after sitting at a light for a while then taking off? I let off of the brake and just give it a little throttle and it sputters/hesitates a bit and then takes off and runs great. Just started doing this, and it is intermittent.

Fuel filter has been changed recently, and I am using blended fuel for the cold.
Also this is the first winter using the Diablo Predator, 60 HP setting. Did not have this problem last winter with the truck. Any thoughts that this is a problem?

If the fuel filter is recent, maybe you got some questionable fuel? or water in the fuel? You can try this...
Drain fuel out of bowl, using valve on back bottom of bowl (about 10 o’clock), take off fuel filter lid, pour it about half full of diesel kleen (white bottle) or stanadyne, turn key to ON, let bowl fill back up with fuel, turn key off, put filter lid back on, turn key to ON, wait for fuel pump to stop whining, then fire it up. let idle for 20-30 minutes.
What this does is two fold, remove water from the fuel bowl, and perform an injector flush. Both are beneficial to your truck.<O

If that does not help, try going back to the stock setting on your chip. I wouldn’t think the chip would cause this, however I don’t have one yet and all I know is what I’ve researched and read here and there. I know chips alter your torque values but PSD’s don’t start really making power until you get the rpms up in to the powerband.
You may want to look into the 10k mod, it will definitely give your PSD some pep off the line, and from what I’ve heard it will not interact with your chip in a bad way.
Maybe some of the other guys with more experience with both will chime in.

You're welcome arno, and thanks for gettin back to us here with your info.
You know....it's kinda nice when a problem gets solved for the benefit of all. This thread not only resolved the 'Romp, Romp, Romp' issue, but me and quite possibly many others discovered we actually do have a block heater. Nice.
Once again, thanks everybody for your input!

OK Rocket, I tried the 'wait till the fuel pump quits humming' trick. Unfortunately, mine never does quit humming. There seems to be two separate things 'humming'. One shuts off about 5-10 secs after the WTS light goes out. The other continues on so long that I gave up waiting after 30 secs (GP's were about to go out!!). The 'romp, romp' was still there in spite of the extended wait. One thing I will note is that it does go away if I put my foot down on the pedal. My romp was bad enough that the engine would actually die on the down swing. Any more ideas??
Last night after work I actually could not start the beast no matter what. It was down to about 0deg F here during the day with a high wind. With the summer syrup that I still have in the beast it simply would not turn over fast enough to get ignition. I wound up killing both batts trying. The Chev guy I work with was getting a good chuckle over this. Unfortunately, no-one was open that had anything under a 10w-30 by the time I got it going so here I am again today at work and it's 'brass-monkey' cold again today. Grrrrrrr!!!

Rocket,
See my post "Still no cold weather start- engine diagnostic OK.
Also "A Simple Stock Solution to ‘Romp, Romp, Romp...." didn't work for me.

Dead Glow Plugs????
I've always run my 95 F350 Powerstroke stock with Rotella 15W-40 oil. The ole girl's got 145,000 miles and until winter '03-04 she never did the 'romp-romp-romp' thing. It got worse in winter '04-05 to the point where it'll often stall during the romping. If I use the block heater, she starts and runs just fine. I'm real suspect I've got a few glow plugs that've died. Anybody got any thoughts on that? Thanks.
