Hello. Any advice, directives and/or recommendation to a good mechanic near 33311 area code is appreciated.

Problem with Oxygen Sensor - had transmission rebuilt in April now being told have this sensor problem and to take to a general mechanic. Would like insight as to cause of problem and if it will cause car to put me down on the road. It drives fine...check engine light comes on from time to time. Any idea as to the cost of this type of job?

Other problem...is my car haunted? Interior lights flash on and off at any given moment. Have changed fuses and it continues. My kids will not ride with me at night; too embarrassed.
