HELP ME! my nicer car just broke down... yeah hah. well the only car i have to drive is a 1985 chevy citation. Its very cold outside, and the car has no heat. does anyone know what could be causing this? it doesnt even kick on. Also, its bogging down really bad, like it sounds to me like when it tries to shift into 2nd gear (Automatic) it bogs down really bad and just recently starts backfiring. The car sounds like the engine is about to blow when it does this. my fiance like floors it, the car jerks and bogs down, and like i said just sounds like the engine is about to blow? can you tell me what this is.
