My V6 has recently developed an annoying habit of stalling. Happens when the foot comes off the throttle and revs plummet to below 400rpm. Tries to recover but generally doesn't make it, and engine cuts out. But sometimes, if you come off just a gentle throttle, the revs manage to stay around 400rpm and gradually creep back up to 750rpm over the next 6-6 seconds where the car will then idle perfectly. The problem has come on gradually but seems to be worse when engine is warm. Could it be:

Air flow meter?
Idle control valve?
Gunk in throttle body?

Would rather have a play myself first before taking into Mazda for diagnostic test!

Thanks for that. I've pulled out one of the plugs and it looks like the engine's running a bit lean. Unfortunately need the car next week for a holiday, so I've had to get her booked into Mazda dealer for a diagnostic check. Hope it's just the throttle idle adjustment that needs playing with and not the air flow meter replacing

You should look around to see if you can get another garage to do it like i did, might be cheaper than a Mazda dealer.

If it is the Airflow Meter, I may have good news for you. I had a spare MAS meter, which I donated to the club 'cause it was going to waste in my shed. It should fit the 1.8 & the V6, so if you find the worst, speak to Tom Tucker - I gave it to him during the Smotter Relay. Possibly some sort of donation to the Club Funds could be arranged in exchange ??

PS : When my Edith has trouble idling, I cure it by wiggling the connector on the MAS meter ...

Thanks for that offer Smotter - very generous. However, Mazda say the airflow meter is fine and all that needed adjusting was the base idle. It's running like a dream now and the cost was a fraction of what I'd feared. Drove out with a smile on my face until......

Went to fill up with petrol and the moron in front of me decided to reverse into me while I was waiting for a pump
Smashed my passenger side indicator and chipped the paint on front spoiler. Still, look on the bright side - loads of witnesses and he admitted liability immediately. At least I should be able to wangle a complete respray for my front spoiler as well as replacement indicator
