1995 960 with 136,000 miles.

Every now and again during low speed, light throttle the engine will begin to run on three cylinders, the check engine light comes on and the OBD sets code 113 OR 115. The ECM detected something wrong and shuts down one or the other bank of fuel injectors (there are 2 groups (1,2 & 4, and 3,5 & 6)

Once the car stalled completely and the BOTH codes 113 AND 115 were set (113 is Injector Group 1 and 115 is Ing. Grp. 2).

This has occured about once every 2-3 months lately until yesterday, when it happened 4 times. If it doesn't stall, I shut the engine off and it restarts just fine running on all six until it happens again.

I've checked the wires to the injectors, something else must be cutting out such that the ECM shuts down the injectors.

Any guesses?

My wife won't drive the car until I fix it.

Thanks
