A/C Engine Bogging Problem

Ok I have a 90 GXL N/A, if u crank the car and turn the air conditioner on the car will drop rpms and if the car is already warmed up it will stall, like if u stop at a stop sign or something, also if the car is idleing it wont hold a solid idle it will go real low and some times die or it will just pulse what can i do to remidy this prob, and it would help if any of u guys have any solutions for the a/c prob...


Thanx

Check your BAC system per the FSM (or Haynes)...

If that's all good, check your TPS & idle per the FSM (or Haynes)

If that's all good, check your A/C compressor for serviceability...

Yes, it should, after it drops a bit, the BAC is allowing bypass air to keep the idle at or as close to 750 as it can, if everything's working right.

If your compressor is on the fritz, the BAC may not be able to compensate for the load, even if it's working correctly...

TPS is your Throttle Position Sensor...

Do you have manuals? You're gonna need 'em, for this car. They can be viewed/ downloaded at teamfc3s.org...
