'79 Bosch CIS fuel injection control pressure to high
I have a '79 924 Porsche which used pretty much the same CIS injection as my 81 & 82 VW Rabbit convertables. Control pressure is only about 4 LBS's less than my system pressure of 75 LBS, and car won't rev up at all. My Rabbits run ok so switched out the warm up regulators with them but no change, wur fuel lines are clear, return fuel line is clear, the plunger in the fuel distributor is free. Don't know what else to check other than replacing the fuel distributor. Help
