I just bought a 06 Pacifica and it just started making a constant clicking noise whether the car is moving or while the engine is running and just sitting in the driveway. The speed of the clicking noise increases as I press on the gas.

No lights on the dash have come on. Car runs great no problems when it shifts gears or speeding up and slowing down, it just makes a clicking noise constantly

I've had done detailed oil changes and fuel system cleanings but nothing changes.

any suggestions would be appreciated..

 

I know I'm responding to an old thread but I couldn't let this pass without asking: Are you sure you aren't low on oil?

I know it's the most basic, obvious thing but it was my first thought when you said the clicking increased when you pressed the throttle.
