i've searched over 100 post's and still could not find my answer to this on going problem.. the problem is when its real hot outside and i turn on my a/c my idle dips real low when i come to a stop. its like im cruising at 3k rpm and step on the clutch. the rev's dip to at least 500 rpm and sometimes lower.. ive cleaned my iacv, changed out my pcv valve, new spark plugs and wires new cap and rotor. cleaned my egr valve. and still the problem persists. and another thing is the car idles real rough like the whole car is shaking.. im not sure what the problem is.. i need some input! btw my car is a 94 h22a1.

any help would be great!!

 

yo, i live in North Sac, have you check the vaccum line and idle control for a/c kick up for the idle when the ac is on. this will put a load on the engine, the vavle should open and kick the idle up???

 

ive checked my vacuum lines and i have no leaks anywhere.. my idle control valve its working b/c the other iacv i had was a bad one.. and when i turn on my ac and rev up and let go of the gas the car just dies.. but now the car idles real low and its close to stalling but catches itself at the last moment. im getting frustrated.. its hot!

 

lol my car does that when i'm low on oil or need a oil change or low on coolant with the a/c on

 

my oil is good and im good on coolant but same problem..

 

sounds like your alternator is taking a ****...check that and your battery...when you turn on the A/C you putting a load on it...see if when you turn you lights on, your hazards, window defroster, heater... every electrical accesory you can think of on and if it gets lower and lower and dimmer and dimmer chaces are its you alternator....or you distributor could be going out??? now that I think about it check your battery connectors and such! good luck
