High Idle Shake
 

I have a 2003 4 door 4 Cylinder EX-L and i have just recently replaced my spark plugs they were white at the tip. My car still shakes when it idles even when warm. I thought replacing the spark plugs may have helped it but nothing, i just had my oil changed as well. the transmission still shifts very smoothly. What else should i check.

what kind of spark plugs did you put in?

The ones the manual says to put in IGK i think, i bought them from honda.

This actually sounds like the problem with the vacuum line on the rear engine mount. Check all engine and tranny mounts. The easiest way is to have someone else put the car in gear and while holding the brake, give the car some gas ..... do the same in reverse to see how much the engine and tranny move. This should help you figure out if any mounts are blown and if so, which one(s). Again, check the rear engine mount for the vacuum line and make sure that there is no leak there.
