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.

When to worry about a check engine light?

A sudden drop in power is much more noticeable and could be accompanied by a check engine light. If your engine seems like it is running okay but is just low on power you are in the right place, but if your engine is misfiring and running rough then you have a different problem that is causing the low power issue.

Is there a reduced engine power ( Rep ) warning light?

Many GM vehicle models come equipped with a Reduced Engine Power (REP) warning light, similar to the Check Engine Light (CEL). 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.

When do I get a reduced engine power warning?

The nice thing about this type of system is that it can be even more instant than an actual hard connection by a cable. The bad thing is, when there is a problem in any part of this system, it can render the vehicle literally un-driveable and you will get a check engine light and reduced engine power warning.
