Cool fuel distributor balance

1991 190E 2.6, this car has trouble with stalling when up to temp. I worked on the upper and lower chambers balance, the end result is 5.4 top and 5 lower, I have free play at the plate and it seems to be slightly rich. Adjusting the co gives me a reading of 0 and -1.23 but still will stall of course when you take it out of idle loop it runs but as soon as you let it contact the idle switch it will stall. I need some more thoughts about this problem. JNT thanks

Support indy shop!

Oh this is hard to find help this way over a forum, go to a mercedes garage they should be familiar with these older cars. Not one servicing newer cars.

When the idle switch closes, it sends a ground signal to the idle relay or the CIS computer - not sure which on this model, and the idle speed is controlled electronically. So something may be wrong in that system, like no air is being supplied.
