Re: EF Not running right
While the engine is running, (if it will idle), spray some solvent or ether along the inlet manifold gasket. If the engine picks up and runs ok, well thats it. It sounds as though the gasket has a leak, also a common fault with these engines.
Also, follow the hose from the MAP sensor (black box on l/h fire wall) down to the intake manifold, this hose does split, and causes a hell of a vaccuum leak, rough running, tons of fuel being used etc. Generally will run o0k up the rev range a bit.
Failing that, clean the throttle plate and bore, remove and clean out and lube the Idle speed controller, which is the cylindrical unit right by the throttle body.
This will suit most E-series Falcons, incl. AU
