well, Basically like the title says... sometimes when I turn on the AC the car shuts off.. What could be the cause..

oh yeah, forgot to add, that it shuts off only when I am not on the throttle..

Not during driving.. https://www.nopistons.com/forums/pub...1047683664.gif

Geez man.. ! Who do I have to **** to get some answers around here?



hahahah

you have to **** banzai!



check for vacuum leaks.......... could tons of annoying crap

Mine does the same sometimes. It's because your BAC is crappy. Mine will stall at first, but will be fine after the BAC loosens up.

It's the Bac.

ok, I had already checked for vacuum leaks. and like Rotary>piston said, once It has been on for bit before letting it idle, it will stay on and not kill the engine at idle.. So the Bac Valve huh..? Is that thing expensive, or can it be cleaned..?

I think I remember reading in the haynes manual that you can clean it...otherwise, just buy one from someone who removed theirs.

Cool, weekend project.. !

there is another fix... i had the same problem last summer there's a wiring harness that likes to come undone especially if you have work done to the motor and a rough idle.... it's just one of those mazda electrical problems. i had the same problem with my car last summer and the wiring harness would come undone and it would sound like there was a vaccum leak somewhere under the hood, but it was just the ac trying to work and it was blowing cold but the car would stall without throttle. before you start investigating parts like the bac make sure every one of thoes wiring harnesses is extremelly tight or you might just have the same loose connection that i had.

I've been doing that.. and have noticed a few unplugged conectors, but I put them where they belong.. I changed the primary injectors, and got to check out all the vacuum lines in there and connectors with the intake off.. Hw bout stuff like bad grounds and and electrical system stuff, could this also add to the problem..

just remove the AC. its a frivolous and unnecessary ammenity anyway. https://www.nopistons.com/forums/pub...IR#>/bigok.gif

Uh, no.. I like to not sweat in my car when it is too hot to put the top down.. Besides, It is fast enough for me.. Even if it does weigh 3000 Lbs, and runs 18's in the 1/4

Try tuning the car up if you havent yet, when i first got my car it would do the same with the ac on when i pulled up to a light. After i got her home the first day and tuned it up and adjusted the idle i had no more problems.

REPU, if none of this **** works, PM me, I'm almost positive I have a couple extra BAC's laying around

Well a tune up is on the list of things to do. so Hopefully that and a good cleaning of the engine and electrical connections and ground connections will help..

Cool, I will let you know.. Thanx

mine does it now and then too, I refuse to raise the idle because

its idles perfect.



It starts and runs perfect, its tuned thats for sure, it will stall

when you are coming to a stop with the ac on right? I just pop the clutch

and get it started again, if its the BAC im sure it can be cleaned in my

case because otherwise the car is running 100%.



Does a sometimes bad BAC hinder performance or just idle?

rob i think the bac only helps the engine under load at idle so to answer your question no it wouldnt hinder performance.

try to spend about 2 hours washing waxing polishing up your car...when i shine up my vert all the little problems seem to go away...probly just coincedence...lol but i have the same problem sometimes...put it in neutral at stop lights when it acts up...or slightly push the accelerator pedal..brings the rpms up to what would be a normal idle...all temp fixes though.

hahaha.



same thing happens to me too... and when ihave a hot chick in teh passenger seat my car doesn't run or idle right...



I think she gets jealous

Yup.. Thats usually the only time it does it..
