Starting to get irritated...My '03 has developed a "hiccup" when at idle. Only happens when its at running temperature. Sometimes, while waiting for the light to turn green, she'll stumble, as if it dropped a cylinder or two. The only code It's thrown was a "fan speed", just prior to the serpantine belt shredding itself, and stuffing itself into the fan and a/c clutches. So far, I've been told it could be either fuel pump, out prop on the injector pump, or an injector issue. Dodge thinks the injectors are going south-when I spoke to an injector shop and gave them the symptoms, they didn't think injectors were the problem. Anyone out there had a similar issue?

 

What's the fuel pressure at idle, hows the fuel filter, in tank pump poss. on it's way out?

 

Not sure what the fuel pressure is- don't have that gauge. The fuel filter is fairly new, has maybe 7500 miles through it. The in-tank pump was replaced at 65,000 miles.
