When this light (or both lights) comes on, you’ll notice the engine barely responding to the accelerator. This is a scary situation if the problem happens while you are driving down the highway or in heavy traffic.

Can a bad MAF cause loss of power?

A bad or going-bad MAF can cause the loss of power. These are usually good to 70K miles. A bad MAF sensor might produce a sudden reduction in car power, but the normal failure mode is a gradual loss of power over weeks. Your engine light may come on if the sensor only has intermittent failure.

What to do if your car has low engine power?

If you notice sluggish acceleration right after some work was done on your car, make sure that everything was connected back properly. Check for loose hoses, unplugged electrical connectors, and loose bolts, and if fluids were changed, look to see whether the right engine or transmission oil was used. Check your tires’ inflation pressure.

What causes low engine power at 40kv?

Check at 40KV and 30KV. If your spark can’t bridge that gap at those settings, you may have worn out wires, a weak or failing distributor, a bad ignition coil or a bad ignition control module, depending on your particular module. Check the tests that follow, and consult your vehicle repair manual for the proper diagnostic for your particular model.
