Hi, my coupe is missing like a bag of hammers. Starts fine but misses badly. Changed cap, plugs, leads, arm, checked timing, all injectors squirting through but it just seems to be massively overfueling, black smoke and all. Don’t know how to do diagnostics on it either which doesn’t help....
Any ideas? Is there an ecu on it and if so, where is it also, where would be the diagnostics lead/port be and what do I need to read it please.
Thanks in advance.
