Customer Question
Hi my car loses...

Hi my car loses power going up small hills and doesn’t build speed also I lose rpms after going 35

Mechanic's Assistant: Is the power loss consistent, or does it fluctuate?

It fluctuates

Mechanic's Assistant: What is the make/model/year of your car?

GMC ENVOY 02

Mechanic's Assistant: Are you fixing your Envoy yourself? What have you tried so far?

Just put cleaning fuels in that’s all some car places said the my sensors are bad but I don’t think that is the problem

Mechanic's Assistant: Anything else you want the mechanic to know before I connect you?

That’s all I have for now
