What do you think about this one...

consistently at 2100RPM's I get engine vibration.
If I had to guess, sounds like I need motor mounts.

Anyone else have to replace theirs at about 35k miles?

 

hmmmmm possible spark plugs too? get Racingline MMI as well!

 

IMO, I'd have to say if it were your motor mounts, you'd probably get engine vibration at all RPM's!!!

 

Good recomendation, however if his motor mounts are bad the Racingline are Motor Mount Inserts which stiffen the factory ones, they are not complete replacements for the real motor mount. I would recommend if he DOES have to replace his motor mount, it would be the optimum time to install the MM Inserts as well.

I already installed the Racingline MMI on the front of my car and it was a b!tch because I had never done it before. So if you must replace the OEM MM, install the Racingline MMI at the same time...

 

that's what I meant, replace MM and get MMI as well. I was in a hurry and wasn't thinking straight!

 

Trust me, I've had my days...

 

Which gear? Low or high vacuum (load)? The EGR valve operates at low RPM. Could be stuck open. PCV valve? Air leak between MAF and throttle body. Cracked vacuum hose. One bad ignition coil or spark plug. etc, etc and then I would check my motor mounts.

Do you have access to a code reader? Many will not trigger the SES light. With a tool like Cipher or Autoenginuity, you can run diagnostics to test each cylinder to see if they fire on time, if they misfire and how often they misfire.

 

Happens in every gear... only at 2100 rpms...
It's odd... can't feel it... only hear it...

 

You probably would feel engine vibrations if the MM were bad, I think.

 

Well, where should I start....car is at the dealership because of weird noise comming from the engine. Originally they thought it was some sort of pulley but since its only on when the blower (no, not the turbo, hehe) is running it was discovered that its the A/C compressor. They are replacing the A/C compressor, belts and .....motor mounts. (43K)
