Q: Engine Light coming on after spark plug change

asked by on

The Engine Light keeps coming on. This started when I replaced the spark plugs. In addition, the car stalls when on inclines.

You may have a vacuum leak from a broken line, loose hose to the air box, or another type of leak. A diagnostic inspection of your Check Engine Light from a qualified technician, such as one from YourMechanic, can help you determine the cause, and fix your issue.
