Just looking for a little insight/help figuring out where to start on this car... started the car this morning and noticed some smoke out of the exhaust but it was dark, couldn't see much.... started driving and noticed that my car was surging and then would steady out... pulled over and called a tow truck to get the car home. Hooked to a diagnostic scanner and the code is p0300 random misfire.... well we started it and there is white smoke out the exhaust, no visible leak, no antifreeze in the oil. When you pull the spark plugs you can smell burning oil. Pulled the intake off and the upper intake has oil in it... car has not overheated... Any ideas?!
