3.5 efi flapper engine . Starts off the key ... ticks over nicely fuel pressure at 9th injector off plenum is 32 ish idle and 36ish revving ... new leads and cap and rotor . Cleaned all I injectors oil flush ... new oil .. rad flush .... etc etc . As soon as driven it feels like 4 plugs fallen out of engine... coughs splutters farts and belching!! Cleaned out petrol tank as was loads of debris plus 2 rubber feet off pump floating free in tank ... made it a bit better ... but is pretty much un driveable as just won't pick up and go . Any further ideas appreciated .
