I have a 2006 e450 u-haul truck with a 6.8L v10.
It loses power as my rpms increase, and if I put my foot in it to try to accelerate, once I reach about 3,000 rpms it sounds like there is smoke knock as if the timing was off. When I power brake it, it won't break the tires loose, but the smoke knock sound isn't there either. (Sorry, I didn't notice the rpms while doing this)
It is not throwing any codes.
The spark plugs are new, as well as the fuel filter. The OBDLinkMX+ code reader was used to check engine performance, including looking at the non adjustable engine timing and everything looks good.
I did fight a little overheating on some long grades, that turning the heater on took care of. Finally, while accelerating I lose my AC. I know that this is a result of a lack of vacuum, but don't know if it is normal for this rig or not.
Does anyone a have any ideas of what my problem may be?
