Note that 10K+ miles were needed to reduce grams of carbon on the valves.* Proven effectiveness. As previously mentioned, check the motor mounts. Perhaps if the "dogbone" aka engine moving control rod, is replaced at the first sign of wear, stress on the other (F & R) mounts can be reduced.

There is an A/C Idle Step Up diaphragm on the older Camrys. It has a white knob on it. The purpose is to increase idle RPM just enough as to offset the load from the A/C compressor when the A/C is cycled ON. When the mechanism is not working or adjusted too low, the natural shaking of a 4cyl engine under load at low RPM is accentuated. Is located on the intake manifold.

This Oregon proposal is before the legislature again. It's a high tech tax grab in the face of expected declining gasoline tax revenues.

"The systems employ wireless technology to calculate how many miles a vehicle travels between refueling, then automatically read this data, compute a total fee, and add this fee to the cost of fuel while a vehicle is at the fuel pump."

One James M. Whitty with the Oregon DOT and the Road User Fee Task Force is the prick in charge of planning this high tech revenue grab.

"Philip®" sez:

Doncha love it when the government proposes a "snitchware" system that you'll have to pay for to be ratted out and cough up yet more $$$s when you fuel up? And, with "congestion pricing" in the mix, it gets even better, eh!!

From a technical standpoint, the systems would be pretty trivial to defeat but since you can't pump your own gas in Oregon, the pump flunkies will be turned into unwitting eyes of the state to make sure you are a good little taxpayer.
