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.....

 

4 cyl. engines are naturally unbalanced, so vibration is always going to happen. Somewhere in your car, a rubber isolator thingie has worn out. You could replace them all, one by one, until yuo find the one that takes care of it, or you could live with it.

 

yea, cause the thing is, other peoples motors vibrate like mine, its just they dont feel it inside on the steering wheel and door panel like i do......

 

different things for different cars.

 

nah i mean even on other peoples ludes.....

 

do each of the ludes idle at the extact same rpm? and do they have the exact same everything? its different for each and every car. i believe so anyway

 

well theirs idles at the same rpms as mine, with the same mod, all i have is an intake..... thing is, there are about 3 or 4 other people other than me trying to find the solution to this..... its not a problem, its just annoying, and its weird because other than that the car drives great so I shouldnt be complaining, but it gets a lil annoying when you sit at a stop light and you feel the car shaking know what im sayin?
