[QUOTE="TARM, post: 1044613, member: 578"] Have you confirmed fuel pressure is fine? The way its happening stumbling then taking off fine and being better once warmed up does not sound like the typical HPOP going bad. Such as with the Stealths its usually the exact opposite i.e. once warm it falls on its face and dies but tends to be good when cold and the oil is thicker. The high IPRs makes it sure seem like something oil related. You never see those kind of ramping up % at idle unless something is wrong. You could always try swapping out HPOPS to see as that is the next easiest step before tearing under the VC. To me the one thing that stands out is what was related to when this all started. i.e. you installed the injectors. Before that everything was GTG right? Seems like that is where I would be looking. Be it oring or actual oil side injectors issues or somehow electrical I think them happening at the same time should be the focus. [/QUOTE]
