Car is an 01 5 speed.

I've backed the idle screw out as far as it'll go to get the rpms to idle at 700-800 with no load. With the ac on it'll sometimes idle down to 200-300 and shutter, makes it feel like the engine is going to stall out. I've checked the vacuum diagram and no leaks that I can locate. Why are the rpms dropping like that? Isn't the car suppose idle higher with a load (ex. ac) on?

 

maybe eld or ur idle bypass valve is clogged.

 

i have the same issue, id like to know how to fix it

 

Do u guys have a cel on? Have u tried cleaning the iacv?

 

no cel.

 

clean the IAC. Its normal for it to drop like that when the compressor kicks on and off..
