When I start it thick white smoke comes out from the exhaust. It does not accelerate like it should sometimes. Seems to be effecting the AC also and the oil light is always coming on.

Good morning.

White smoke is an indication of burning coolant. The most common reason is a bad head gasket.

The AC will not work if the engine is running hotter than it should be. The condenser cannot function if the engine is running hot.

The oil light will come on if the coolant is in the oil. It will thin out the oil and the pressure will drop.
