Just changed the spark plugs on my 2001 cls with 92000 miles. Changed the front 3 and drove it for a day and seemed fine. Then changed the back 3 plugs and noticed a slight vibration in the steering wheel at idle. Acceleration seems smmoth and slightly improved with the new oem plugs 2 motor mounts were changed about 80000 miles
so dont think thats it. Anyone have a idea what the cause is?

Thanks.

I think that maybe the gap is off on one of the plugs. Just eyeballed it before install.
Been working alot so will pull the plugs and regap in the next cuople of days. The service manager at keyes acura said that this may be the culprit.

 

Check your motor mounts too. Very common problem to have replaced especially with a CL of that mileage

 

He just said he replaced motor mounts at 80gs brotha.

 

same thing happened to me, but it was the mounts

 

Found a small thin black hose loose with one end not connected to anything. There was a metal tube near the engine cover in the back it attached to. Must have accidentally nocked it off. Reattached it and now no vibration.
