i have a question about throttle body.. i wanted to clean it up in toyota service center..
 
but they said its not necessary to clean..cuz the reason why i wanted to clean is that if i turn on the airconditioner..
 
the engine is shaking..also the RPM is around 500..
 
they said thats not the reason...n i asked them what the reason is? they said..thats normal there is no problem..
 
i feel bad if the transmission is on D or R.. cuz its shaking..what should i do? pls help me~
 
 
 
 

With engine warmed up and idling check idle RPM, then turn on the A/C.  The engine should idle up to compensate for the increased load of the A/C compression.

Note: The compressor cycles on and off, thus RPM will varing as this happens.

If the engine RPM does not increase but drops there is a problem with the idle up circuit.  The RPM with A/C on should be around 800-1000.

As to shocks, if a Toyota dealer did the job the cost is inline with what they charge; parts and often labor are higher at the dealer.
