hello

im new to this forum, i've been googled to a few of the forums here so i thought it would be a good idea to come try it out

so i have a 97 acoord with almost 110k miles on it
the car runs perfect there is nothing wrong with it
but when i warm up the car and the rpm drops to its
normal rpm the car begins to vibrate
also when im at red lights the vibrating begins once again
when i touch the gas pedal lightly the vibrating seems to stop

so i was wondering if the throttle body is the problem or something with it

im not much of a car person, i try to make sense of things tho

 

Is it 4-cylinder or V-6? Automatic tranny or manual? These things matter...

If it's a 4-cyl automatic shift into N & tell us if it still vibrates like that. Automatic tranny cars have a vacuum-operated rear engine mount that's supposed to make itself softer when idling in-gear.

Otherwise (whatever engine & tranny you have) what is the idle RPM? Should be 750 or 800 for a 4-cyl. If that's too low, then you can think about setting the "BASE" idle speed. There's a procedure for that - don't just crank on the idle stop or (worse yet) the throttle cable.

 

its a 4cyl with automatic transmission.

in neutral the cars has a faint vibration at times none

um the bas rpm is at about 800 or maybe even 900. thats what my friends that said

if you need any other information, let me know please

 

I have a 94 accord ex 4 cylinder. My car does the same thing. The rear motor mount is a hydraulic mount controlled by a cable attached to the throttle. The linkage on the mount became disconnected and was no longer being adjusted as the throttle was pressed. I suspect either, the linkage became disconnected as mine did or the mount itself has failed. This is actually quite common on these cars.

Hi,
Could it be possible if you have a digital camera to take a picture of where this cable should be attached to? because I'm not sure where exact that cable is
and I cant ask my dad (car mechanic) because he doesn't like doing anything anymore. Plus, he probably doesn't want to help.

 

I don't believe there's a cable. My '98 would be different because it's 6th generation. But there should be a solenoid valve that controls vacuum to the mount (it's not hydraulic). Then there's a vacuum hose from the intake manifold down to the mount.

 

Here it is for '97. #3 is the vacuum mount & #9 is the solenoid valve.


The one for '94 (below) looks almost the same...

 

Well, as a matter of fact I just repaired the cable linkage on my rear motor mount again today because my previous attempt failed. Unless I"m hallucinating, the rear motor mount has a cable attached from the throttle to the mount.

The linkage is underneath the mount. It is visible if you look between the rear of the subframe and the rear of the firewall. You have to look from under the car. It's hard to fit your hand through there. I actually had to use long needle nose pliers to perform the repair. If you use jackstands or such, please be careful. ( 1994 accord ex automatic ) and it's white, if that helps. heh.
