"FOR RAE 190-- CIS-E COMPUTER"

HEY RAE, DID YOU YOURSELF TAKE THE CIS-E COMPUTER APART AND RESOLDER EVERY COMPONENT OR DID YOU HAVE SOMEONE DO IT FOR YOU(LIKE AN ELECTRONICS SHOP, COMPUTER ETC...) I'VE HAD TECHS CHECK-OUT THE STALLING IN MY 86 16V AND ALL I GET IS"I DROVE THE CAR AN IT DIDN'T STALL ON ME" OR "CHANGE THIS CHANGE THAT", BUT THEY WOULN'T TELL ME IF WHAT THEY WERE TELLING ME TO CHANGE WAS BAD OR NOT-?
I BELIEVE AS YOU'VE ALLREADY FOUND OUT THAT THE STALLING IS DUE TO (MERCEDES LACK OF PRECISE COMPUTER ASSEMBLY PROCEDURES)

With the stalling as intermintent as it is, it's very hard for a shop to troubleshoot. I guess that is why they just tell people to replace this and that, yet it never fixes the problem. I didn't replace one thing on my car, I didn't have to after talking to so many other people that had replaced everything possibly related. Knowing that I started to think it must be a loose ground or a cold solder, due to the fact it might go for months without stalling and then one day stall 50 times on me. I hadn't been able to find a loose ground, so I removed the CIS-E computer. I have been working with electronics since I was 12 (my dad who is an EE taught me) so I am very comfortable with electronics. I resoldered every component in the CIS-E computer and the car has never stalled since. This has been almost a year ago. There is one other person I know of that has done this too and his no longer stalls either. I have never talked to anyone else who has been able to eliminate the problem. It must have simply been a cold solder (which makes sense to the symptoms). The CIS-E is basically a fuel management computer, so it could easily cause the car to stall.
