Message: [QUOTE="6.0 p-stroke, post: 381159, member: 242"] My dad's 6.4 has a weird issue between 1800-2000 RPM, if you let out of the throttle while accelerating at about 1800 RPM it will keep pulling hard up until about 2000-2100 RPM. Even while just cruising the RPMs hang for a second or two before dropping when you let off. It acts like it tries to runaway but then stops. I've heard about a few 6.4 runaways but I thought it was injector related, and Ford has done almost all of the work on it under warranty so I figured they would have seen the update. The truck is an 08 with 190,xxx, it has H&S tunes (he keeps it on the 250 tune), intake, exhaust, Elite studs and EGR delete and intake elbow. It also seems to smoke more than other 6.4s I've rode in, there always seems to be a slight haze no matter what. Has anyone else had similar issues? What could be causing it? [/QUOTE]
