Throttle body is clean. Had catalytic converter changed 2 years ago. THis usually happens in hot weather and idling in traffic, or in hot weather when I stop accelerating. Not hard starting. Take 2-4 times to start.

passenger side will switch to hot and will not switch back or blow cold, until the motor is shut off and restarted.

Stability light is on

It stops clicking after 25 mph

what is the cost to have an idle arm replaced
