It would be interesting without that switch
At last my 3A engine without that switch iddles at 2k rpm
Btw why u will replace throttle body? If I understand correctly, intake manifold will be original? Larger throttle body can only cause problems in city driving when less air are needed - I have problem like this - when I'm driving @ 55-60 kmph @ 4th gear [1,7-2k rpm], there is very small gap when iddle switch switches on and ECU switches to forced iddle
