This happened on my 04' T (tip) today and a couple of days ago.
Started the car, everything was perfect. Put in reverse, the engine choked a bit, went below 600 rpm, and then turned off (hope that made sense). Started the car up again, and everything was fine.
The same thing happened a couple of days ago.
My amatuer instinct tells me it may have something to do with the fuel filter, maybe bad gas?.

Any input would be much appreciated.

Thanks in advance.

 

does this only happen on warm up???

 

The last 2 times it happened was after the car was left for about an hour or so, max.

 

This has started happening to me also. Every now and then when reversing out of a parking spot (when the car has been sitting for less than an hour), it dies when I disengage the clutch to grab first. Doesn't happen when the car's cold.

 

Did you figure it out?
