Hi Mike, I tried all you mentioned but for the injector cleaner. The leads all OK, all vacuum hoses checked, found one small pipe leaking and fixed that. Problem now car kept getting worse and ran real rough. I disconnected the fuel supply pipes to the stainless pipes supplying the fuel to little fuel filter thingy connected to the vacuum system with a small pipe to the underside of the intake manifold. When I removed the wire clip holding the little filter like thing down and removed it, I could see fuel pumping out by switching on or off the ignition with key. Wondering if the whole problem not caused by fuel starvation? Not sure how to test for fuel pump activities?
