4.0 OHV Hesitating/Sputtering

4.0 OHV Hesitating/Sputtering
200835 Miles.
When you punch, stopped or rolling on the highway it will hesitate and sputter. Just put a new FPR in it. Fresh fuel. Think my Fuel Filter is clogged up? Anyone got a link to a location or a DIY? I want to get this done before we got up to the Dunes in two weeks. Isnt the filter on a frame rail somewhere?
Thanks a TON!

You'll want to pull the fuel pump relay (or trip the inertia switch) when changing a fuel filter in order to release the fuel pressure.

I had the same problem. I pretty much went through all the steps recommended on this site, and FINALLY, it's running strong now. What I did in order:
1. Changed fuel filter
2. Changed IAC
3. Cleaned MAF sensor
4. Changed PVC, changed Spark Plugs and Spark Plug Wires
5. Cleaned throttle body and "Seafoamed" it
After I did each one, the symptoms improved, but soon came back. I'm hoping after this last thing, the positive changes will stay. So far on day two after last intervention, and truck running very strong. If this fails, I may look into changing the fuel pump. Hope I don't have to do that.

I Finally Fixed It!

So I did a search and read about the 97's having a crappy paper gasket between the lower intake manifold and the fuel rail (I have a '98 4.0L OHV) which caused air leaks and made the truck have symptoms similar to this. So, I printed out the "how to" and changed this gasket along with the three gaskets between the upper intake and the fuel rail. While I was in there I also cleaned up the upper intake, the throttle body and the fuel rail. It pretty much took me all day (especially trying to pry the upper intake from that damned EGR tube). Took for a test drive and had no sputtering/ hesitation. I'll post several days from now to see if this comes back. So, I did all of the above in my quote along with the gaskets. I really do hope this sticks. I did not do the coil pack thing because mine looked good. But, if this comes back, I guess the next step would be the coil pack, then the stupid fuel pump.
Some helpful advice, don't bother trying to find these hoses anywhere else but the dealer. These hoses have to withstand high temperatures, and the autopart store guys were trying to sell me vacuum hoses for windshield wiper applications saying it would work. The two hoses (at least on my 98 ranger 4x4) were even a different size from each other. One was 4mm and the other 5.6mm. Just go to the dealer and pay the twenty bucks for the two hoses.

After all this, have you tried using carb/fuel injector cleaner? It could be as simple as that...your injectors could still be clogged despite running cleaner gas through...I have had this problem on mine (the sputter on my 1997)...I changed the fuel filter too, but it turns out I jsut needed to throw a couple of the bottles in for a fix.
*shrug* It's about $5 for 2 bottles....give it a shot!
