ac making idle drop 1500 rpms?

if its dropping and almost stalling when you come to a stop maybe you have a crack or something in your brake booster hose that goes from the brake booster to the intake manifold, they are known crack after 20years lol

but it only does it when the ac is on...
so i dont think its anything like that
 
Already wrote that in the first page.

gah i was half asleep when i wrote it.. and i thought that i read it somewere.. lol

but it only does it when the ac is on...

the thing they are trying to get your to fix first is your high ass idle. the compresor being on the motor should not affect it idling at 1500-2000 rpms. and then once you turn it on it drops down to 500. there is some kind of vac leak somewhere would be my guess. but paul might be right too and it could be electrical.

i cant belive that you think having the motor idle at 1500+rpms is ok?


maybe the clutch is toast on the compresor causeing a lot of drag?

i know yall think i dont know shit but have did you check the compressor itself b4 it was hooked up? also wat about the refrigerant and oil levels. Its highly unlikely to overcharge it that much but you might want to look in to it

its only when the ac is on
the motor has never once stalled till i hooked up the ac

and when the compressor wasnt hooked up and i would jump the low pressure sensor it would bump up the idle

so what else could it be

did you try jumping the wires at the connector w/ the compressor hooked up?

ok so i had to view this post to see what retarded ass coment you made.

first off you dont know shit. I dont care if you got lucky one time with rodds shit.

second. if there wasnt enough oil it would just kill the compressor and would not affect the idle.

third if the a/c system was over charged and o-ring would have blown. again not affecting the idle

fourth if it was undercharged it would not have come on at all.

come on i mean did you really even read my first post
it clearly says i turned the idle up to prevent it from stalling

never mind
ill figure it out

and the ac system was vacuumed and charged two days ago
he pressure is at 250 @idle which is where it should be

i read it but i dont get why you would. obviously there was a problem... look for vac leaks imo.

and i figured that you vac'd and charged it right... but ya tu sabes.. he just wasnt sure

i didnt get lucky with that shit, ive worked on a car that had the same problem. if there wasnt enough oil the compressor would begin to seize and increase effort would be need and if the belt tension is tight enough it could still spin but bring the rpms down. the thrid and forth one i already knew and is why i said highly unlikely

you did get lucky and your still living off that one time you helped someone... and if i recall correctly you said that you were working with your father who figured out the problem with that one car.. so you cant even take credit for coming up with the idea

of course i wasnt sure. ppl go out and by those cheapo walmart cans and just fill till it gets cold and then figure more = colder.

as i recall it was rodd who had his pops helping him. and im not living off of that. rodd is the one who keeps saying that i was right on his shit. and when you guys posted that you have never seen me give useful advice i didnt jump in and be like i helped rodd figure his shit out.

prob just too much of a draw on the battery. get a multimeter and check your battery should be between 12 and 14 vdc
 
Yo Niii If You Hit The Iacv With A Hammer Or Ratchet It Will Become Unstuck And Probably Work If Its On A Dumb Nissan Motor And Then You Will Be Able To Bwoop Bwoop In Third Gear Clutch Kick Your Life Away!!

this fixed it!
ive been bwoop bwooping all day!
 
idk i know the pressure wasnt too high because i had it on a gauge when i was vac/charging it
but the high pressure safety valve for the ac popped
so no more freon
