Car had engine light on for a year, but running perfect. This springtime the engine light was on sometimes, off sometimes. Car started stalling with no warning. Dash would display - HOT.......A/C DISABLED. Car would usually restart no problem, but might stall again during drive. So far mechanic has replaced temp sensor, ECG sensor and ECM(i think that's what it's called). Hasn't stalled for 2 drives to work and back, hopefully problem solved.
