CIS is fine when it works. Once they sit for a period of time stuff gets gummed up and stops working. A new (rebuilt) fuel distributor will run you over $200. New injectors are 40+ each. I have seen people swap out 1 or 2 parts and have a good running CIS car. I have also seen people change every single component and still have headaches. If you can’t sort the CIS out swap in an ABA (MK3 4cyl) into. You are certain to get mad Bros in that car. Give germanautoparts.com in Clifton Park a shot if you need parts.
