Q: Q: Check Engine Light is on

asked by on

Engine light keeps coming on; and vehicle loses power when traveling up hills, and occasionally on flat land, and when it's idling.

My car has 98000 miles.
My car has an automatic transmission.

Your check engine light may come on for many different reasons such as a faulty mass air flow sensor, a faulty O2 sensor, a bad catalytic converter, bad spark plugs or wires and many other reasons. Unfortunately due to the wide range of possibilities for the check engine light to come on, the best way to narrow down the scope of what may be causing this is to have the vehicle hooked up to a scanning tool to download any potential fault codes that may have registered in the computer. I would recommend having an expert from YourMechanic come to your location to take a look at your vehicle to determine what may be causing your check engine light to come on.
