Question: The check engine light seems to come on often during this time of year when the outside temperatures range from a low of 50 to a high in the
70s (in Florida) and the humidity/morning fog is heavy. My mechanic checked the error and he says it was caused by a "mis-fire" on one of the plugs, consistent he says with the above mentioned weather conditions. He says some moisture could have gotten into the system. Sounds reasonable to me, but just curious if anyone hear has had this problem. Thanks for the input!
