CHEVROLET AVALANCHE ENGINE PROBLEM

2003 Chevrolet Avalanche • 60,000 miles

Electrical noise is heard through the radio, when on, and engine is running. Noise increases with engine r p m. Could this be caused by the alternator or something else?

Sounds more like spark plug wire interference do you have a portable am/fm radio?
