Solving intermittent car problems can be challenging for both the customer and the auto mechanic. A new customer came into BA Auto Care and described this series of problems:
- The check engine warning light came on intermittently.
- The transmission warning light came on intermittently.
- The engine misfired in cold weather.
We documented the problems on the job ticket, talked to the customer about how we would approach the diagnostic work, and provided an approximate cost.
Our next step was to road test the car. As often happens with intermittent issues, we were unable to reproduce the issues. No misfires occurred and no warning lights came on.
