Can a bad alternator cause reduced engine power?
BAD ALTERNATOR If it’s faulty (especially when producing higher voltage or when the bearings are bad) it can put extra load on the engine and reduce engine power.
What to do when reduced engine power comes on?
If you’re driving and the reduced engine power light comes on, the first thing you should always try to do is get the vehicle back home or to a shop immediately. If you’re already at home and the light comes on, don’t drive the vehicle.
Why does my car have a reduced engine power light?
This sensor also aids in transmission shifting as air enters the engine. If this sensor can’t communicate with the vehicle’s computer systems to regulate engine revving, the vehicle will go into limp mode and trigger the reduced engine power light. What Can I Do to Fix This?
Why does my GMC have reduced engine power?

What causes a car engine to lose power?
It is possible that a related fault may have the computer “think” that another circuit or component is failing.
