I never learned much about Bosch CIS fuel injection because even though I've spent a lot of time wrenching on European cars, the vast majority were either carbureted or had timed mechanical injection. By the time non-timed-mechanical injection was widespread, I wasn't much in the repair end of the car biz anymore.
Well, the DeLorean has CIS with Lambda, known as K-Lambda (exhaust-gas oxygen sensor feedback), and it has problems...which it had when it came in for all the custom work.
I'm having to wade into it with a vengeance, and have bought all the factory and aftermarket CIS books, including the factory Volvo 760 GLE manual (the 760 used an almost identical PRV V6 as the DeLorean).
There's a lot to know, but it's just another machine, and of course it's entirely logical IF you approach it methodically and have all the specs, references, and diagnostic procedures available.
I was kinda dreading it, but it's actually a lot of fun learning a complex new (to me) system, and the bonus is that my '74 911 has pre-Lambda CIS, and after getting the DeLorean sorted, I should be competent to straighten out the Porsche as well (even though the plan is still Weber carbs, just because, it'd be nice to be able to enjoy the car a little with the CIS before I do the swap).
