Customer Question

34_W 2 months ago
My 2001 Mazda Miata MX-5 just died while driving. First the radio went off and on and finally shut down. After driving trying to get home had no power to go. I pressed the gas peddle and will not go fast until finally died. This is my third battery in 2 years or so maybe 3years. I do not know if it is the battery? I replaced the alternator last year. It was running fine for a year and now the car died while driving. Does anyone know what it can be? I am currently recharging my battery, but i feel it is something else besides my alternator and battery.
JA: Is the power loss consistent, or does it fluctuate?
Customer: If I stop it will be totally dead
JA: What is the model/year of your Mazda?
Customer: Seems to surge
JA: What year is your Mazda?
Customer: 1990 MX-5
JA: Are you hoping to fix this yourself? What have you tried so far?
Customer: Cam Position Sensor replaced, alternator replaced, battery replaced
JA: Anything else you think the mechanic should know?
Customer: Ran for about 1 year after CPS replaced, and ran for 2 weeks after alternator replaced.
