Still acting funny, and I am no closer to figuring it out !!
could it be from running lean ? Its acting all kinds of "odd". I plan to bring it to the shop friday to tinker some more. SHould be slow enough to have some time.
Another thing to add, right before this started happening, I did the "gotts mod" type deal on my intake, to open it up some. Also dropped in a K&N air filter.
I also was feeling some "shudder". If you get up to speed, about 60 mph or so, then let off the gas and let it slow to roughly 40 mph, then slightly get back on the gas to get back up to speed, there is this violent shudder. Entire truck shakes, and does so very HARD and rapid. It feel like washboard road at 70 MPH. Knock some kidneys around ! Let off the gas, or turn off OD and it stops immediately.
Any help is hugely appreciated !!! This one has me scratching my head some.
