I have a 06 Acura RSX Base Model Automatic. There is a high vibration @ idle and accelerating, there is no check engine light ON. I tried everything, replaced all 3 motor mounts plus the Transmission 1. OEM Motor mounts. Complete Oil filter with spark plugs Air filter. Checked the Hub assemblies on all wheels. I even sold my 18" rims thinking that was it and went with the stock 16" and nothing. I do have Advanze Tein Z Damper suspension which is about 6 motnhs old and only drive the car about 20 miles everyday. no other Mods. This just annoying driving with that vibration that I'm to the point and giving up and just sell the car as is : ( Any suggestions of what could it be??? PLEASE HELP!!!!

 

Some have reported that tightening the engine mounts following a specified sequence has helped. Also, have you checked your ignition coils and fuel system to ensure you are running on all 4-cylinders?

 

Also, pull engine codes and see if there is a 02 sensor issue as that sensor can cause vibration issues when it goes bad. Even if your engine light is not on check for codes.

 

I'm no automatic trans guy, but my parent's corolla has a similar problem and we were told the torque converter is on the fritz, might be transmission related?

 

thanks vrrodrri but I have tried the sequence on the mounts lots of times thinking maybe I did wrong or something. No I have not check my coils nor checked to see if I'm running an all 4 cylinders. Will do this weekend I'll have to spend my long weekend working on it. But how would I do that? Do i just pull one coil @ a time and fuel system idk it runs perfect it's just that vibration that's killing me

 

thisguysaves thanks man I'm not an automatic guy either it was just passed down to me but I have read on other threads about being the transmission hopefully it's not that. Just to mention it does take a while to shift gears from 2nd to 3rd. Maybe 😓 that would suck.....
