My A/C acts like it not cooling at idle, but going down the road it's ice cold. Any ideas, thanks
check the pressures hi/lo side and record the air temp of the day of testing. post the pressure readings.

at an idle the air flow is dependent on the fan , so the fan may be weak or not on. the fan must be on when ac on.

next check that the condenser coils are not blocked . check also between the cond/radiator coils.

possible the compressor is not pumping properly so at idle rpm less flow of the refrigerant at higher rpm you get more pumping. this may also be ac compressor clutch slipping.

you have electric or mechanical fans ????
