1995 Chevrolet Monte Carlo Z34 3.4L MIL Lamp on, MIL LAMP ON & OFF
engine light is on & off intermittantly, there is not a specific pattern. we retrieved code # 1640. we ran through tests for this code & all is ok. cust did originally complain of oil light on dash all the time, which we traced & replaced low oil level sensor....
