Car shakes really bad when in drive and reverse. Rpm's are constantly jumping and is worse when the AC is turned on. (My AC is broken too at the moment). All the lights flicker a little. I have changed the spark plug in cylinder number four twice. Also, the check engine light randomly turns on and a day or two later turns off, and so on and so fourth. What can I do to fix my problem?
