It actually runs rough/slow also when its cold, but once the whole engine heats up its ok. which is more the reason why i think thats the issue. I could be wrong, its just what i think, it already has the stancor gpr, but it sits around alot in the last few months, and this problem has developed while its sitting. It just really makes me think thats the problem is all. But the stancor gpr is less then 60, and if youve never done a gpr on your truck, its not a bad idea to do so.

Reps to Dan, Great offer. If your service engine light come on, there should be codes. Remember, not all code readers will read PSD codes. Could be a bad ICP or IPR sensor. Mine acted something like that when my IPR went bad. Also, you might want to rig a fuel gauge up and check you pressure.

I'd definitely recommend reading the codes. But..I can say that I had 4 injectors replsced and started having a rough idle and very poor performance (until warm) immediately after the injectors were put in. Took me a few weeks to convince the shop to just replace the injectors....they did...and that problem went away. In the end, I'm not sure if it was an injector(s) or an o-ring on an injector. Never smoked at all....just poor idle and poor performance until warm...you could literally feel it 'kick-in' and run fairly normal once it was warm. Hope this helps. Codes would also start leading you in the right direction.

The "ROMP, ROMP, ROMP" (symptom #1) when cold starting is indicative of fuel starvation. There have been many threads about the cold starting "ROMP, ROMP, ROMP", but it is easily solved by allowing the fuel pump to fully fill the filter housing during the WTS period prior to ignition. This is why I believe it may be a fuel delivery issue. I get "ROMP, ROMP, ROMP" no matter HOW many times I cycle the key.

I've got the Actron CP9125 PocketScan. Doesn't say anything about not reading certain types of vehicles?

Put synthetic in it and the romps will go away. Believe me I know. You need to check your fuel pressure with a gauge, at idle and under load. Once that is removed from the equation we can dig into it. Since you are not getting smoke, it is probably not getting fuel. When mine romped it smoked.

It would not surprise me if your scanner was not reading codes.

There's a guide to the HPOP at the bottom of this page http://www.forddoctorsdts.com/articl...icle-06-08.php you can download for free. It kind of explains how all the parts work. Hope this helps.
