Default stalling problem

Im experiencing a stalling problem when I come to a stop. It seems like it only happens when warmed up. I only have 18k miles, but from the searches Ive done Im thinking the ISV needs cleaning or the DME needs to be replaced. I'll probly do both.........any other suggestions?
Thanks....

Get a new DME and try that first... it's easier! If that doesn't solve the problem, then buy a six pack of beer, invite a buddy over to help, and clean that damn ISV.

I followed the above steps and everything turned out great! Good luck.

Plug in a new DME relay first.

Similar situation with my car. It would stall when it was warm and I couldn't restart it until it cooled down again. It turned out to be the crank sensor.

I forgot to mention that I disconnected the battery prior to this "stalling" problem to clean up the cables.
As for the DME, it will be here tomorrow.......do I need to disconnect the battery to R&R the DME?

I believe that if you disconnected your battery, your car will have to "learn" to idle again. If I remember correctly, this will take 30 mins or so driving/idle time. Mine sorted itself out in 2 trips.

I read that somewhere on this forum, the car has to learn again after a reset?! Well, I'll change the DME and do the ISV cleaning and take it out for a long drive.............hopefully that will be the ticket.

Then the first thing you should check are the battery connections. Sometimes they look fine but they're not tight enough and you end up with stalling problems or your alarm acting all weird or your alarm acting weird and causing your stalling problems...

Are you serious? you just purchased a DME control unit because the car is stalling or am I missing something here.

Hopefully they're talking about replacing the DME relay and not the DME control unit.

Shu,
Save the $$$$ DME for return - each time I have disconnected my battery, the car would stall on throttle lift off for most of a day, or idle far too low: as Michael noted, get in and drive it .... so the DME can relearn to idle correctly ....$0.00 cost, and some driving fun.

The ECU will learn in no time with a few good full throttle accelerations throught the gears.

as long as you have purchased the dme fuel relay already i'd go with the new one (if the old one isn't the problem i'd just keep it as a spare). i've had my battery disconnected 3 times and never had any stalling problems, but since i've had every other 993 problem you can have (knock on wood) i am glad i finally dodged one bullet.

Agree if it was a relay purchased ... however, Shu said a DME, not a DME relay - there can be a thousand dollar difference .. , plus the fun of pulling the drivers seat, etc: I'd do a lot of checking prior to flipping out a DME ... especially as the car starts and runs.
