I have a 96 4.3 vortec with about 115,000 miles. There are several issues I am having with my truck. The first is that I have a mixture of gas in my oil. Along with raw fuel sputtering out of my exhaust, with the gas there is a constant cloud of white smoke being emitted. The engine runs rough and idels just as bad. There were several codes that came up: MAP sensor, Mass Air Flow sensor which were replaced and random misfire on all the cylinders.
the problem just happened as I was driving no other warning signs. Email add is fluntag@yahoo. Com thanks for the help
have the same problem?
