Re: it keeps stalling out

How does it start when after you fill up your gas tank? I had the same problems and it ended up being the purge control solenoid valve. Mazda replaced it under warranty.

Re: it keeps stalling out

it's possible it's the exhaust gas recir valve but usually there is a c.e.l. associated with that.
maybe if you can be a little more specific, we can help diagnose it.

Re: it keeps stalling out

id pull codes if u have a cel, if not, id almost bet on the purge valve, it can cause lean conditions and low idle, this is becoming more and more common

Re: it keeps stalling out


I'm not getting a cel ill start the car it'll idle fine then eventually start studdering and bogging down then eventually stall out and sometimes when I stop the rpms just drop and it shuts off. The only reason I tthink its the egr is that mazda told me it needed to be replaced before and I thought the dealership was just trying to choke money out of me.. So I never even looked at it

Re: it keeps stalling out

A lot of stupid stuff can go wrong and never throw a code, check you air filter, spark plugs, and make sure their is no oil on the spark plug boots. Run some good injector cleaner through it to clean your lines, and make sure their is no water in the system. All of these are $5 fixes, no problem.

Re: it keeps stalling out

So I checked my cai and the coupling was lose from the throttle body so I tightened it and now it won't stall out but its still studdering and idling extremely low
