Nope
Nope, you aren't alone. My parents old 91 wagon and my 93 accord 10th ave had it. Now, I have mine stopped completely, but I sacrificed something to get it. First, there is a screw that is located at the throttle body, right underneath the hoses that go to the map sensor. I turned it out about a full turn or two, and now it idles really high when I turn on the car (about 1500), but then when it warms up alittle, it doesn't vibrate, and it idles at about 800 RPM. The problem stems from the car going down to about 500-600 RPM at idle at a stop light. So now mine idles good, but at start up I have to sit there for about a minute and let it idle down. Then I am good to go. I haven't tried it yet, but I believe that changing the timing alittle could change it possibly too. Then I could get the airscrew back to normal. I haven't messed with it yet, but plan on it someday.

idle
Yeah H22Accord, I think that screw is for the idle as well, and that is what I am saying is the problem. The cars idle too low. It has nothing to do with the mounts, etc. It is all about the idle being super low with a automatic. That is why the standards don't do it. When it is in neutral, it idles fine, but when it's in gear, it runs the car down to about 500 RPM. What other cars do you know that idle smooth at 500 RPM? Mine doesn't do it anymore since I adjusted the idle.

u are right about the timing belts... my car is almost perfect or perfect but only after it warms up, when i first turn it on is on higher rpm than before with the old belts but once it warms up goes down, almost 0 vibration. the only thing i didnt like about the way the mechanic change my belt is now i waste more gas since it has more pickup/accel than before. now all i want is be able to have the car turn on and not hear a thing just like when is off, even though sometime my car is so quite i think is off lol well maybe the intake needs to go heh
