2007 Toyota Camry vibrates when at stop and the A/C IS Running, already check the ECU, also Engine mounts, Body Throttle and butterfly flushed, fuel injection system flushed. Took it 2 Dealer and they have same problem with other customers, maybe if enough people complaint about it TOYOTA HQ might issue a repair bulletin or something? Just tired of this bad vibe......:(

Just doing a visual inspection on an engine mount is not good enough. The rubber mount may just be bad or the engine mount attach to the frame is broken. If mounts are fine then engine balancer is deteriorating.

Clean the throttle body bore and plate of any carbon deposits. Also, clean and check the IAC idle air control circuit . If it has electronic controlled throttle body it will not have the IAC. Carbon deposits around the throttle body bore and plate (butterfly) can restrict airflow at idle causing the low uneven idle.

check engine mounts there mite be a loose or broken one, works fine while driving but is a problem when starting and stopping

Hello

At the point where the air intake hose is connected to the engine is a part called the "throttle body". the TPS is attached to the outside of the throttle body. See picture below.

Engine temp too low is usually the thermostat, was this replaced too? If not, replace it. Might check out the fan clutch and the engine coolant temperature sensor.

As far as the vibration, have you taken a look at your tranny mounts? Usually vibrating in gear while stopped is the engine mounts, but I've seen the tranny mounts cause this too.

Also, check out the upstream 02 sensor and make sure it's operating correctly. Have you changed your fuel filter?

Also, just making sure.....You did have the battery disconnected while cleaning the throttle body right? If not, just unhook it again for a minimum of 30 minutes. After that drive around for 20 minutes to reset the computer.

While several mechanics couldn't find anything by using their computers, some of these will not throw codes if they are just about ready to fail.

Anyway, some things to double check here. Hope at least some of this helps, because it sounds like you're doing the right things.

4cyl or v6?? is the chk engine light on??

If V6 camry, remove air duct on the throttle body and spray solvent (carby/ throttle body cleaner) down the opening just before the actuall throttle blade, be generous

Clean the IAC. Disconnect throttle body air hose and you will see a hole on the bottom of the throttle body just before the butterfly valve. Spray throttle body cleaner down the IAC hole and then let it soak about 1/2 hour. Reconnect hose and run engine about a minute and then repeat this process 2 or more times. Toyota engines from 1997-2005 commonly have the IAC get cruded up with carbon as early as 35,000 miles. This is a sImple and cheap repair that many repair shops don't want you to know.
