The fuel injection K Jetronic and KE Jetronic is a robust system. Small things can cause some bigger issues. I6 and V8 M103 M104 M116 M117 engines were equipped with these systems. There is a small pre filter on the fuel distribution that often gets overlooked with some nasty repercussions.
Especially cars that have sat around for years should be inspected thoroughly and the fuel system should be inspected closely and cleaned.
