Ive changed absolutely everything, ignition, throttle position sensor, map sensor, ecu, dizzy cap, rotor arm, leads, checked timing & compression, its all spot on.. fuel filter, starts an idles fine, even unbolted the manifold incase exhaust is blocked .. earths are ok, no air leaks. Diagnostic test/ No fault codes. soon as try to rev, it wants to bog an cut out 😂 The fueling/air has to be wrong as brand new plugs are now solid black and cannot figure it out.
