i thought wen u burn oil theres grey smoke so i dun think its the oil. everytime the car is on a bit of oil shoots out the back occasionally, still wet oil not burned... anyone kno is wrong with it?

 

sure its oil? could be water & carbon from the exhaust.

 

also a puff of black smoke comes out wen i shift gears

 

black smoke is unburnt fuel. burning oil makes a bluish white smoke.

 

anyone know how to fix it thought?

 

hmm.... thats a tough one. first thing to try is reset the ecu. get into the underhood fuse box and pull the ecu fuse and leave it out for 15 minutes, id go ahead and leave it out for 20-30. then replace it and start the car and let it idle at least 5 min. if that doesnt help, then check your spark plugs and wires and cap and rotor. if you havent replaced any of these in the last 50-60k miles, go ahead and replace them. just go with stock replacements unless you are going to be running an aftermarket ignition and/or FI.
