:dunno:The TB started shifting hard on the way home. The check engine light as well as check guages light came on along with service stabilitrack. The temp. guage was showing cold. After stopping at the house and trying to start it didn't want to. It sputtered for a few seconds before finally starting to kind of idle ok but there was smoke coming out of the exhaust. It would not rev smoothly and when put into reverse, again with a vicious jerk, the rpms fell to low and it died. We had it towed to the garage but it was already closed so I won't find out till tomorrow what the heck is wrong with our truck. I have no idea what would cause all these lil things to happen at the same time or why all of a sudden when it was running fine yest. when we parked it.
