[QUOTE="Bobs 7.3, post: 1457128, member: 8460"] It seems if I just run it easy say normal driving it will not romp say little here and there to none but if I get in it good then it will romp at idle a lot. Not a bad romp like I had when cold and old tired injectors with 15-40 oil but more as a baby romp. If I put it in the high idle tune when hot or cold it romps a worst then baby romps. Start up it only cranks 2 to 3 revolutions and fires right off every time hot or cold. I may try making a ipr removal tool and I have a rebuild kit here and maybie the ipr has something in it causing it to stick who knows as I haven't had it out in 5 years. Change oil every 5 to 7k miles and have always run 5w-40 t6 rotella for the past 8 years with no problems but maybie back to 15-40 delo oil wouldn't hurt even the motorcraft oil but I haven't heard too much on that stuff. Could be time for an Adrenalin pump and pull the old stocker. Also next time it starts romping Ill shut it off and try unplugging the icp (even thought it and the pig tail are new and it romped with the old one I took out) and see if it does romp then. If it does then ill try leaving that unplugged and unplug the oil temp sensor as that will eliminate 2 of the 3 items that make up the feedback to the ecm and if it still romps ive been reading its either the ipr or a weak hpop. What would I need to make a mechanical pressure gauge to test the hpop? [/QUOTE]
