Hi guys, when will it ever stop 
Every week something else seems to go wrong with my so called "ultimate driving machine"
I'll try to explain the problem as best I can
.....here goes....
I start the car, I almost always let the automatic choke cut out before I move off, sometimes if I drive away before the auto choke switches off, when it eventually does swith off, the car will run very rough when at idel in drive or neutral, so rough at times the engine dies. I turn the car off, let it sit a while and then it goes fine after. No error messages or lights on dashboard.
At a guess it seems to be an air mass meter or fuel pump issue. The problem does not happen every time the auto choke switches off...it's very intermitant, so hard to take to a garage to show a tech the problem.
Have any of you guys or gals any suggestions as to what it could be?

It shows up no errors, before, during or after it starts running rough, my money is on the air mass meter, I had a friend of mine at the local Toyota dealership run it on their diagnostics and it showed up two error codes but no explanation as to what they were, only said the codes were "dealer specific" anyway the car is off to the BMW dealer next week...so should know more then, thanks for the replies guys.

My Ride: 2004 BMW E60 530i, upgrades: Magnaflow exhaust, Mtec angel eyes and low beam head lights, Just purchased 172 style wheels, looking around for the best tires on Tire Rack now. R1 concepts rotors drilled/slotted. Saving for the M-style kit from Trinity Auto.

Hi guys, took the car to a BMW main dealer for them to run on their diagnostics machine...guess what, no error codes, stored or otherwise?????????? At least they fixed the battery connector that was recalled.

I haven't got a clue ????? nothing showed up on the main dealer diagnostics machine, on the plus side, they gave it a software upgrade...free......and the rough running hasn't happened since...maybe coincidence though.

Because your friend at the Toyo house erased the codes. They updated your software free to lock you down to their server/equipment lol. this resets all adaptions so it's probably not coming back, If it does start with air/fuel/spark

Hi guys.....this problem is back again, after months of perfect running, it's acting up again. It seems to be the same issue, every now and then, maybe a few minutes after starting the car and driving away, it starts to run really roughly and sometimes so bad, when you stop, the engine dies. I'll turn the car off, leave it half an hour, start it again and it runs fine.....what the hell is wrong?
