The idle speed sounds about normal for an engine at operating temperature. In fact, 800 - 1000 in park/neutral sounds a little high.
So, I don't think this is an idle speed issue. That doesn't mean the engine isn't running poorly, just that the idle actuator is able to compensate if it is.

What should I try to be able to solve this problem.....Could it be a faulty
spark plug, a faulty fuel injector, a defective head gasket.
Could it be the motor mounts.
Local mechanic found no error codes on computer, but his device looks a little
beat up. I've been using the car with an engine check light on for the last

I'd also be particularly interested in the check engine lamp. If it's on,
there should be a code in either the engine or transmission control module.
Depending on the situation, it may provide a clue as to your vibration pr
Three years ago I has the ECU checked and the code was something about the
odometer, this worked fine, so I disregarded the engine check lite.
I doubt that my problem is the transmission because with the transmission in
park, the same shaking occurs when I switch on the AC, only to a lesser degree.

If the lamp has been on for three years, there's little reason to expect that there isn't a new problem now. If the lamp is on, there are codes present. I have no idea why your mechanic couldn't retrieve them.
