hey, I have a 99 prelude, base, 5spd, 54K miles on it....... and when it idles it tends to have vibration on the steering wheel...... the idle does not fluctuate, it stays steady, and it stays at around 7 or 800 rpms, so its not because the idle is too low..... I checked the front three mounts and they are ok, just cannot get at the rear mount to inspect it so maybe this could be it.... here are the things ive tried to solve it which didnt work..... spark plugs, wires, dist. cap and rotor, TB cleaner, fuel injector cleaner,octane boost, also, it will do it more when i use power such as headlights, a/c, windows..... someone suggested to me that it could be the battery so i have yet to replace that, it also seems to do it more when the weather is cold outside, even when the car is fully warmed so someone told me it could have something to do with the coolant..... I did a compression check and it is ok so thats not the prob, I am out of ideas, any insight would be greatly appreciated, thanks, also, the valve lash is ok they are not too tight so that isnt the prob either.....

 

Have your timing checked. It is rare, but H22 motors can fall out of timing very easy when pushing the redline constantly. I know this because my 96 lude did it a couple of times, but it is rare. This tends to happen because the h22 motors distributor advances timing a little more when it reaches its vtec point than other vtec motors. Just have your timing checked. Or, your pistons are doing whats called "walking" which is when the piston moves side ways in the cylinder. Could also be crank bearing failure. BUT, this is VERY unlikely considering the year of the motor. I seriously doubt this is the problem. But have your timing checked.

the ignition timing on the distributor? i can check it but the problem is, there is no way to adjust it on my car from what I hear......
