Engine : C16SE 8V Dis pack
Symptoms : Sooty exhaust, engine buckarooing off throttle, fine when foot the floorboards, plugs are stinking black with soot but are dry.
Solutions tried :
New plugs, ignition leads, swapped DIS packs, tried another ecu Coolant temp sensor, changed the lambda sensor 3 times with different known working ones.
Going to try next :
Hoses , to and from the inlet manifold, and the inlet manifold gasket itself. throttle position sensor, MAP sensor and hose.. if these solutions fail to succeed im stumped!!
Any ideas folks??
