My m30 has some bad juju. I'm the 2nd owner - it has a 107k and was owned by an old lady.
The big problem right now is that after some period of driving (usually more than 30 minutes, sometimes over an hour), the card will just randomly shut off. It runs fine up till that point, with no missing, hesitation, anything. Sometimes it will go days without a problem.
I've run out of gas enough time in my life to recognize the symptoms, and this is completely different. It doesn't loose power and die, or sputter and die, it just.....stops, like you turned off the key. It will start again but die within seconds, sometimes longer. Sometimes it will run stop run stop, like someone is flipping a switch. If it sits for 5-10 minutes, it will usually run like there was never a problem. Sometimes it takes longer. No matter what, the car will always get home.
I've opened the hood while it was running and wiggled everything. No luck, but I did learn that my injector connectors were on their last leg and replaced them. I did all the normal tune up items - cap, rotor, plugs,etc. It runs fantastic now, but no change to the stopping problem. There is a usually vacuum released when I open the gas cap to fill up, but opening the venting the tank has no effect on the car when it is having an 'episode'.
I'm tempted to rule out fuel issues because of the lack of sputtering, but I don't know anymore.
Any ideas?
