another one 1990E Engine stops when hit the full brake.
 

My 1992 190E 2.6 has a lot of problems.
1.The right mirror stops working last week.
2. The tach guage jumps up and down like a compass and now dead.
3. The engine stops whenever I hit the full brake. But if I press and let go and press it again , it's OK. It seems to me that when it runs at a slow speed the engine is going to stop.

Other than that it's running great.
Thanks
