Little power if you just get in and go. push on the gas and doesn't go. blows blue smoke if it doesn't run for a few days.

Hello Aaron, Bad valve seals can cause your engine to smoke after start up and clear up after a few seconds of running. Sometimes the valve seals become hard and brittle. They can break up and restrict the oil return holes in the cylinder heads, causing oil to seep into the cylinders through the valve guides.

That is probably the head gasket leaking. White smoke is from antifreeze going through the exhaust. The engine compression is pushing the water out of the radiator.

blue smoe is the sign of burning oli. it ban be rings or valve seals

Hmm, is this an older car? Blue smoke on start-up is usually a sign of a very minor oil leak going past the rings.

I normally do not consider this to be a problem if:

1. The car has sat for an extended period of time.
   
2. It only happens on the initial start up and doesn't do it after sitting for an hour or so.
   

white smoke would be a sign of a head gasket blue smoke is a sign of burning oil black smoke is a sign of a fuel problem so blowing smoke and rough running do a compression test and look for a weak cylinder

White smoke for a diesel means air in the fuel system. You will have to start at the engine, I start at the line going to the fuel pump. Get some fuel in a can, remove the line to the supply side of the pump and put another line from the can to the pump. If it starts and doesn't smoke , then you have to work your way back to the tank and find the spot that is sucking air. If it doesn't start the I would replace the filter first, check again. There is a possibility that the injector pump is bad, but these don't usually throw white smoke. They just make the engine have very little power or no start.

give me more info about your plug, is it black by oil or black powder from gas ?
in the other hand, smoke white is a motor cold on winter, smoke blue is oil inside motor, smoke black is gas not burned,
so be shure exactly what color is...

Hello white smoke is usually engine antifreeze,Blue smoke oil burning,Black smoke car running to rich on gas,gas is not burning properly.

The pressure regulator is most likely the problem,but have the codes read to make sure.

Rich fuel=black smoke.
Oil burning=blue smoke
Coolant burning=white smoke
