Gramps Posted July 24, 2021 Report Share Posted July 24, 2021 So, this has happened to me twice now on my 2011 Boxster S, both times after a lot of driving over a few days (road trip to Lake district last year and another to Cornwall this month), the car is all warmed up but I'd stop at lights whatever for a short while and the engine stalls whilst idling, no rough running prior, just cuts out. It starts straight away and runs sweet as a nut again. But I found this time round that if I re-start it and let it idle for 30secs or so it would stall again. I tried this same procedure 4 times and each time it stalled after about 30secs and started again clean as a whistle. It does occasionally try to save itself from stalling and gives itself a squirt of juice which would keep it running but roughly. Again if I re-start it it runs clean again, If I re-start and pull away before the 30secs are up it's fine. Anyone out there come across this before or know what it might be? Air flow sensor or the like? TIA for any help....Rob AKA Gramps Quote Link to comment Share on other sites More sharing options...
Paul P Posted July 24, 2021 Report Share Posted July 24, 2021 My car would do similar but would be second start after cold start. So out the garage. Turn it off. 5 mins later start and it would fire, run, die. I had a service recently. They changed plugs (otherwise just a minor. It’s not done it since. ) same / different who knows but that’s all that changed on mine. Quote Link to comment Share on other sites More sharing options...

May get round to changing the plugs soon anyway. Will have to see what develops if anything 👍 Quote Link to comment Share on other sites More sharing options...
iborguk Posted July 25, 2021 Report Share Posted July 25, 2021 If it were mine I'd stick it on a code reader and see if anything is being registered. All the best re sorting it. Quote Link to comment Share on other sites More sharing options...

You aren’t that far away from me and happy to help if I can. Quote Link to comment Share on other sites More sharing options...
