190e cuts out, flat spot Intermittent Fault

[darren_c_smith]

when warm, engine either cuts out when car comes to a stop or if it does idel, stalls when you pull away. Restart engine and runs perfect until come to a stop again.
also intermittently mis-fires/ hits a flat spot when slowing down from speed then re-accelerating.
