'87 260E
For those of you that helped with my rich running 260E (post cis-e ecu)
It turned out to be a bad f.i. ecu. I plugged another unit in and now I can run the car all day with no black smoke out the back and a great idle.
Now it's running great, why are the these models so hard to start hot or cold. I see several posts but no answers (or maybe I missed them).
Once again thanks for the help guys.
