Ok quick question 2006 tsx when you have motor running and sitting there the car is perfectly smooth but you put it in any gear then you get a really bad vibration in car what to look for?
I did replace awhile back the front, rear and side motor mounts but not genuine acura but they did say they were all hydraulic. what should I look at next?


Thanks!

 

If idle speed is going low (< 600 rpm), vibration may occur. Idle speed in gear should be about 800 rpm. Low idle would be caused by too little air passing throttle plate.

Cleaning throttle plate and bore may help. Careful not to force throttle plate open manual (use gas pedal w/ keyswitch On to open for cleaning).

good luck

 

Somewhat thing happened to me. My problem was the spark plug. Engine struggling to keep my car on and it was shaking when I held the breaks at a light.

 

You really should have replaced them with genuine honda mounts. I have found that aftermarket engine mounts actually made cabin vibrations a lot worse compared to genuine ones.

 

I had the same problem, I bought cheap Amazon mounts and the problem got worse, I ended up replacing the front engine mount with a genuine Honda mount and my car runs smooth again.
