Ok.....so here recently if im sitting at idle and I have the A/C on my 94 vic dang near dies on me!! The rpms go to about 100-200 and engine shakes like its about to die. I assume this is happening when the compressor is on but WHY? What do I need to replace?

As Always..................thanks for any comments and suggestions!!

 

Is the A/C having problems or noisy? If not, try cleaning the IACV on the throttle body. Another possibility is a problem with the A/C wiring that tells the ECU to ramp up the idle speed when the A/C is turned ON.

 

check your altenator

 

A/C not noisy or abnormal! When driving its fine but when I stop and motor is idling it jumps down to LOW rpms and motor shakes around (i guess about to die) ! I wouldnt think that its the alternator but Ill have it checked!! Any additional help would be fantastic.

Thanks

 

****Is the IACV the idle control valve??? Ill chek what I can and clean.
