Lynn,

It sounds like most of the problem is with the mechanics. The CIS system is not an easy one to deal with, even for a Bosch certified tech. A dealership most likely does not maintain a staff that is capable of dealing with issues on a car of this age.

Try and find an independent Bosch certified shop. One that will do a bit more investigation before using the "wholesale" parts replacement approach. Taking pot shots in the dark will indeed become very expensive.

Even for a DIY type these cars require alot of attention.
