Hey !! Nice forum !!

Looking to buy a Honda accord for the daughter. 1993 wagon with 129k miles. Original one owner vehicle that appears to have been well taken care of.

The car runs and drives real nice, BUT when you come to a stop sign with the brakes applied you can feel the engine vibrating. The seller says this is common for this vehicle and that he had motor mounts replaced. He also said he had the timing belt replaced 3k miles ago, but that the motor vibrated long before the belt replacement. Owner says it is normal and no cause for alarm.

I would love to buy this car but I just don't feel right about buying a car for my daughter with a vibrating motor. What do you think ?????? Thank you all in advance. John

 

heavy vibration in a cabin i usually a motor mount. Which mounts has he replaced, there are four

 

This is a pretty common ailment for accords, especially 90-93's

I have a 91 wagon with the exact same problem.

However, it's nothing horrible and you get used to it after a while

And if it really bugs you, or your daughter, you can apply a small amount of pressure to the gas pedal to raise your idle RPMs and the shaking is completely stopped.

For a more permanent fix, you could change the positioning of the throttle cable to raise the idle level. And you can go back and change it at any time.

 

Pulling the throttle cable tighter IS NOT the correct way to change the idle speed.

There is a small amount of adjustment in the front sub-frame motor mount.
At the top of the "dogbone" loosen the bolt somewhat, then with the engine at idle, put the car in reverse [while someone holds the brake] and then tighten the bolt.
This method loads the bushing for a better cushioning effect.

Honda Service News "If the H in the center of the steering wheel is not vibrating/moving, there is not excess vibration"

 

I found the best way to stop the vibrations and "smooth out" the idle is to install NGK Iridium IX spark plugs...You can use the stock wires, but the Iridium plugs will help smooth out the vibration at idle...I installed them in my 1991 Accord EX Sedan (F22A4 block) and almost immediately noticed that at the factory-set idle of 750rpms the engine feels and sounds like it isn't even running. No annoying vibration, no noise, just calm silence, but a bit more punch off the line.
