Can anyone solve this or know of anyone

1993 Honda Accord 10th Aniv Edit, 2.2 auto, approx 150,000 miles radiator and coolant sensors have been replaced, this ONLY occurs when the
air conidition is on - if you stop the car and put it in park then go to shift into drive the shift lever will lock up, goes into a very high idle, if you unlock the shifter with a 2nd key and start to go the brakes will not work, feels like there is no vaccum. If the car is turned off and restarted it might run normal. Also have a problem with idle pulsating revving high and low, not sure if this is all connected.
Thx Tim
