[dalmation53]

So today i started my car in the a.m for work. as soon as the car was warming up I hear like a humming noise coming from the engine( I belive is the engine) so when i'm applying throttle gently is like hum hum hum hum with a whistle sound. As soon as i left off the gas and put it in neutral coasting sound goes away...car has 100k miles so new noises anybody have an idea? Car isn't vibrating or anything. But it seems a little laggy then before.

Likely your diverter valve. Theres some posts in the DYI I believe that tells you which version to purchase or if you want to upgrade.
