"easily damaged by dirt or moisture in the fuel, some parts are
expensive, and few know how to fix it."
that's why few are on the road.
I have also seen them just crank and crank and crank and can't fire
up...though of course, something was out of spec.
don't tell anyone ..but a push button switch wired to the cold start
injector makes a fine manual fuel primer !
Every junkyard Benz that had CIS has had it's main fuel control unit
pulled off it ..and parts are sure expensive and hard to get.
Personally ..I just never had a problem with intake valve deposits on
any engine really.
stay cozy and safe everyone ! Scott Jim Lahey

> I am very familiar and a big fan of CIS or CIS/E, (O2 sensor). Any of these systems have a lot of opportunity for engine enhancements. Very simply as the engine sucks more air you get more fuel. The downsides of this system is that it is easily damaged by dirt or moisture in the fuel, some parts are expensive, and few know how to fix it. A fuel pressure gauge and valve set are more important than a multi-meter. The death kneel for these systems was emissions requirements and the issues with intake valve deposits and valve guide wear. The major disadvantages was the inability to turn the injectors off when the engine was being overrun and for the CIS-E to respond fast enough to O2 sensor input. My 88 fox has the CIS-E, I had a 560SEL with it and countless other VW's including a 79 Sirocco, and 81 Rabbit convertible.
