After a run in my 5 pulled up at home then the car started to misfire badly and cut out.The vehicle would only restart while pumping the throttle.Fuel you think, well 4psi to carb 2 carb changes no better. Ignition tdc change ,aei change spark is present different cap rotor leads.Found air leak at inlet manifold stud,removed head to helicoil it refitted new h gasket kit and bolts. Compression tested b4 and after this all results good.There was no wash on the head or pistons present no visable damage anywhere?Checked dizzy was turning ok thats good too,different fuel pump relay checked fuses.The model is a 1.5 i beleive e reg,aei in scuttle cant see any overboost wires did this model or the phase one have them.Any help on diagnosing the fault would be great cheers.running out of patience jason.
