My 92 GSR shacks at idle. What is causing the shacking at idle?

It's a vibration that can be felt on the steering wheel.

I have 120,000 miles. Distributor cap and rotor, ignition wires, coil, ignitor have been replaced already. I have not changed out the sparkplugs yet but I am going to install NGK Iridium sparkplugs.

 

all hondas shake at idle when they get some miles on them, chill.

 

I think he might be somewhat right..most cars will have vibration. I guess for answers though... maybe check your tranny, engine mounts and just make sure the rubber is still good. Car is a 92.

btw. u still have the b17 in the car?? nice to see a g2 gsr still out and about.
