i got a 04 6mt 8 at 59500 miles with engine replace last year at 47000. after comming back from vacation for 7 weeks. as I start driving my 8 a few day ago. I notice the car started to blog and die...it just keep on shaking and die, if I gas the car, it will move like running on just one rotor.. sometime it will last about just couple second, but sometime it will last for a while. at the same time, cel will blink, but as soon as the blogging stops, the cel will just stay on. and one more thing...the lower coolant light seems to come on more often then before...but I checked and the coolant level is ok...and it doesn't leak and coolant...anyone know what might be happening or suggestion if what I can do before taking it back to the dealer....Its seems to get less after a few days of driving...but it still happens once in a while.....pls help

 

nobody have any idea what might be the problem?

 

First off, you should have posted this in the Issues & Problems Forum.
Now on with your problem. We need to know what error codes are in the ECU. Get those and we can begin to troubleshoot your problem.

 

rofl, another one of those 2-3 post newbie who never bother to search and expect ppl to spoon feed them.

 

if your car blogs i'd get it a livejournal username.
