I ran the car on saturday and attempted to chage the heater valve in firewall but stopped as I saw the hose in the dash will need replacing. I refilled the coolant tank, started the car and put her back in the garage. She ran fine at that time. On thursday I started the car to take her for inspection (DMV) and she startedr oughly and died. I started her again and she died. This process continued for a while and I noticed a creaking or clicking sound as if some eliectical componant was trying to connect. When the car start it bucks and appears to be choking out. I need help-----helllp,thanks
