2006 Chevrolet Avalanche

Interior problem
2006 Chevy Avalanche 6 cyl Four Wheel Drive Automatic 20,000 miles

I took my car to jiffy lube for a service, they cleaned my fuel injector for 59.99. Next day a light comes on in my car, it is themalfunction lamp. I took my car to a dealer who said jiffy lube damaged my fuel injector and it would be 480.00 to repair. Jiffy lube said that is impossible as they only flush ir out with cleaners. In the meantime the light is still on in my vehicle and it wont pass an emissions with this light on. What should I do?

Some of the injector cleaners on the market can damage the GM injectors. I recommend cleaning the injectors with GM top engine cleaner diluted with gasoline. You can also use Chevron Techron fuel system treatment. Watch out for jiffy lube.

Just use Top Tier Gas and you shouldn't have to worry about dirty injectors or carbon build up.
