Car Vibrating While Idle

Car Vibrating While Idle
I have a MY08 Sedan and every so often my car will start to shake/vibrate while in idle, mostly when the car is in park. I've cleaned the TB and taken it to the dealer who says "everything is fine" and of course the car didn't vibrate while they had it. I was wondering if I should clean the MAF sensor. I searched these forums and couldnt find much about it. Does anyone know how to clean the MAF sensor and where it is located? Thanks in advance.

I never dealt with a bad motor mount yet but I doubt there would be any vibration when the engine is under load. Just pop the hood and observe how much the engine moves when you step on the gas.

Hmm . . . I'm not feelin this whole motor mount theory. It seems like it would not be intermittent if it were a bad mount. We need a bit more information from the OP though, like are are the rpms fluctuating when it does the vibration. I'm thinking this is just a "shiver" caused by the engine rpms dropping and then catching again, which could happen regardless of motor mount conditions. Besides that, I can't recall hearing folks reporting bad motor mounts on these, so it seems somewhat against the odds. If the idle fluctuates, then I'd just be looking for what may be causing that.

I do agree with you that OP needs to give us more info to assist in troubleshooting, but I would not disregard the motor mount just becuase it is intermittent. If his RPM are fluctuating then I would have to say that the motor mount is not the problem.

I have a similar problem but only when in drive. It started out just a slight vibration and it is starting to get worse. It is mainly noticed when waiting at stop lights. Pretty heavy shaking and the rpm's are around 850. Will check out tomorrow and see if there is excessive motor movement when revved.

Usually vibrations only at idle are a sign of a mount going bad.. but for a Nissan and so soon seems unlikely

I had the same issue with my 08'. However, my idle was low (around 600). After cleaning the TBs and the MAF's the issue never went away.
I took it to the dealer and thier solution as they told me was to reset the idle portion on the ECU which actually worked. It still has a very subtle vibration every so often at a stoplight but thier solution stopped the annoying (message chair) vibration I was getting originally.
