What color is the smoke? Black=unburnt fuel, white/gray/blueish = oil. If it's oil, could be piston ring(s) just for starters, among many other scenarios. Black would be injector problems, or ICM , the 'brain' bad, not sending the right fuel- air mix ratio, bad plug wires and/or plugs causing misfire ans no spark to one or more cylinders, fuel passes thru uningited therefore not burned and passes through, there is the black smoke. This is a very short list of what could be wrong. Run a fault scan, see what code comes up
