I tried to go to school this morning and the car wouldnt start. So I waited until later today to try to crank it. Nothing happend at all and then I finally turned on. Turned the car off and tried to crank it again and big cloud of smoke came out of my air filter. I opened the throttle body and saw smoke coming from there. Before this happend sometimes while driving the idle would jump while my foot was on the gas. Checked the compression and it was fine. Also checked the manifold gasket and that was fine. any clue?
