Default Re: Buzzing noise in throttle body

Unless you are given better suggestions from another member, please heed any suggestions given. I replied to your private message.

You're dealing with electronic fuel injection and electronically controlled throttle/ electronic pedal. Your car has the most sophisticated electronics possible and not diy friendly with home repairs unless you have advanced knowledge in electronics, EFI systems, drive by wire throttle, diagnosing and troubleshooting vehicle electronics. No carburetor, no distributor. All electronics.

The main parts of EFI systems in this car are; throttle assembly, pedal, ecm, all sensors and fuel pump. Whether you know it or not, you're diagnosing and troubleshooting on an advanced level most diyers will not understand due to electronics playing a major role in most vehicles.

REWARD EXCELLENCE!
