Hello all,

I have a 1992 300e 2.6 w 103 inline 6. The vehicle for some time now has been hard to cold start. I seem to have luck by cycling the key on and off two times to allow the pump to build pressure. Not sure but that seems to help.

Second symptom has been getting progressively worse over time. The car stumbles upon acceleration after a stop. This morning I actually needed to get on the car and it stalled completely and would not start for about 5 minutes.

This stalling stumbling problem seems to occur when the car is just warmed up on a cold morning.

I am at a loss so far on this one. Any guidance would be greatly appreciated.

Thanks!!!
