Idling and now starting issues.

After driving 250miles south she was running fine. I filled up and shortly after had what felt like a misfire. the truck was driving fine but it just wasnt idling like it used to. I put another 750 miles in the same week and have filled up 2 or three times now and it still isnt idling right. i changed the fuel filter and now a day later its not starting right. it will turn over, choke a couple times and die. then i have to crank for about 6-10 second with nothing and then she will fire and run. I my lift pump is just over a year old and my pressure sensor recently died do to lack of isolation. i have plenty of power all around still and my fuel mileage is still the same. you can tell also if you hold the throttle down to 1200rpms or so, it doesnt run perfectly like it used to. im at about 139000 miles in this 01 24v. Did i just get a bad dose of fuel and it may just need to still work out its issues? Im going to replace the filter again. any ideas would be greatly welcomed.

I would re-check the fuel pressure if you can... Then if the fuel pressure is good I would consider pop testing the injectors... Might have a sticky pintle... Don't ask how I know this... :duh:

yeah after reading something you had posted on injectors that was my first thought with the misfire feel. i was debating tearing into the injectors and trying to clean them. what kind of places will pop test the injectors?

    I actually ran a full tank down with 32 ounces of Power Service Diesel injector cleaner in the gray bottle. So far it is running a lot better and I found out the starting problem was because i was leaking fuel from the fuel pressure sensor. I tightened it up and have not had any starting issues. Thanks for all the input!
