smoking from where? what color is the smoke

Answer 2

RPM problems like you are having are caused by a leak in the intake manifold or air plenum. But if it isn't doing it all the time it may be the air bypass valve located on the throttle body. I am curious as to the color of the smoke. White??? ,gray,??? blue???

Answer 3

you could have a blown head gasket.

Answer 4

well, first problem is it's a mustang.....(sorry, i'm a camaro fan). anyway, i'd take it to a mech. and throw it on a dyo mach. sound like a carb/ inj problem to me.
