RPM Needle jumping and blowing white smoke
After driving hot for a little while the RPM needle starts to jump around and the exhaust is blowing out white smoke and sounds horrible. When it comes to a complete stop the engine sounds fine again. It also while driving at highway speeds of 55-60 mph the truck shakes. It had also been randomly cutting off while driving down the road. Need help now.
