'01 F250 started missing.
Hi , My 2001 powerstroke has started missing. I filled it last week at a truckstop and after parking it overnight it started right away but with a bad miss. I live in southern california, so cold weather wasn't an issue.(keep reading please, I'm a republican). after it warms up the miss dies away and the engine smooths out, although it is hard to tell if the miss is completely gone. the truck has 170,000 miles on it, all of the fluids are kept up and changed when due, I reprogrammed it in 2002 with a superchips reprogrammer, set at the + 70hp towing setting. I installed the banks engine brake, banks gauge pack and the transmission lock module. I also installed an AFE air filter. I changed the fuel filter 4000 miles ago. what I'm doing so far is to use up as much of the fuel as i can before putting in some sort of additive to get rid of water-my first thought when it started missing. however, after reading the posts in this forum I'm confused as to what the problem might be. ford replaced that sensor whatchamacallit in 2007 and I've never had a problem with this truck.

Well, lets break this down some for you for some places to start looking. Any check engine lights on the dash? Did you try running the truck without the chip installed? Have you used that truck stop before (quality of fuel)?
Another thought is to but a bowl under the drain tube of the fuel filter, open the drain and drain the bowl empty and see if there is water in the fuel. Then, turn the key to the on- position (don't start) with the drain still open and see if there is a steady stream of fuel coming out or something maybe plugging the pickup foot in the tank or your pump is dying. How low was the fuel level before you filled up?

thank you Chris, the gauge was on empty when I filled up, there are no check engine lights on, yes I've filled up there before, and I've got to wait for my wife to get back with the truck before I can physically check for water and fuel pressure. I want to add that I was on the freeway yesterday and I stomped on it to see if I could clear it out. the truck got with it right away, there was a big black cloud first time i did that but the truck ran really well. My wife is the main driver and she never gets on it, so every once in a while I do and blow out the cobwebs. anyway after it was parked and cooled down it started up with the miss.

What temps are you getting to, what oil are you running.. sorry, this sounds like the romps to me. Might just be time to change the oil, but Syn would be the best choice. Again, what temps are you dropping down to?

hi Pat, since this has started we have had two nights where the temperature has dropped to 30 for a few hours before dawn, light frost, but usually it's in the 40's at night and 70 ish during the day. typical So cal weather. I've been using shell rotella 15W40 for years. the oil level is just barely down from the top mark on the dipstick and I've gone 3200 miles since the last oil change.

Here is something to look at, I didnt think of it, although I have been tilting them back for a bit.. Not that it would have made a difference, I didn tthink of it. Post 2 https://www.ford-trucks.com/forums/1...h-running.html
Still looking though!!
A great description of the romps from another great memeber here.
"The EBPV's don't work on either of my trucks. Deleted the one on my 97 when installed a new turbo. The romps are different. The romps sound like you hitting the gas and letting off real fast. Like reving the engine from 1000 to 2000 rpms real quick. You would not drive with the engine romping if you have an automatic. My truck does that on occasion, and I would not shift it into gear with the engine carrying on like that. Switching to synthetic is not a bad idea. I run it in both of my trucks. That said, my 97 still romps occasionally".

This is a post from Chris.. Outstanding person. So is John whom that last quote came from..
"The romps are typically associated with below freezing weather, and caused by the cold thick oil not being able to properly fire the injectors in our HEUI system. Sticking poppets inside the injectors (most commonly caused by not paying attention to oil drain intervals) can also cause this. A sticking IPR is another possibility.
How old is the engine oil, and is it full? "

I was just joking around b/c I thought what you wrote was funny wh. I did not feel comfortable enough to try and walk through your problem but I am extremely curious as to what you find.

thanks Pat, I checked out that post and it's not what is happpening with my truck. his problem is much worse than mine. my oil is five months old, which is a bit longer than it usually takes for us to drive 3k miles. but if you are suggesting that an oil change might help then I'll be on it tomorrow. it's due anyway. I've never had a problem with gunk build up and my oil always looks in good shape when I change it. I use a bright yellow drain pan and always look for anything crappy when I'm putting it in the used oil bucket

I am sorry, no I wasnt saying that you were not changing the oil, I was pointing to the romps, as you might have seen Chris put together other possible causes.
I have had the romps since the first cold day I have had the truck, and I have ALWAYS used syn. I wasnt trying to lay down any claims like an oil change. You will also see a note there about the UVCH might be loose. I beliive the other was the IPR. I was just putting in front of you what the causes are to be, as thick oil not getting through the fuel injectors until it warms up.
