Engine management systems

CIS and L-Jet are the engine management systems. It controls the air and fuel mix for optimal running.

It looks like CIS ended in the 1979 MY for US cars. Which means unless your car is a Euro, you have L-Jet. Does your car have a fog light to the left of the rear bumper? If not, it is a US car.

Which is good news, because my impression is getting CIS to work right is harder than the L-Jet, but that may be just me.
