[W126 Coupe] HELP! Car Salling!!!!!

[David Fatovic]

do you remember where you found the computer and
wiring harness. I will want to check that out as well

I changed the fuel filter tonight. it did make some
difference. here is what I found while driving it
tonight. it goes well while driving, but when you stop
it doesnt hold idle very well or at all. that is when
it will stall. it tries to idle around 480-500 rpm. I
believe that is too low to keep vacuum pressure. what
could cause this? I did replace the over voltage
protection relay.

any ideas now? what should I look at to adjust the
idle?

thanks,

David
