Mechanical Fuel Injection

Porsche MFI overhauled

Some early MFI Porsche’s are getting on now and many not be running at their optimum. Hundreds, if not thousands of movements in the throttle bodies and in the mechanical fuel pump itself are bound to cause wear on moving parts, allowing air to pass through the spindle bushes, corroded throttle chocks or even a worn 3D cam in the pump itself. Mechanical fuel injection, if working correctly, is a brilliant system. However, if there are issues it can be a headache – poor starting, poor running and poor acceleration are all possible problems.
