I tested the module on the coil pack and swapped coil pack with a known good one off a mate's car, while I was there I changed the airflow meter, throttle body, blanked the egr, injector loom repair, I've got a new fuel filter to go on. I've also sprayed around the inlet manifold to see if it leaks air and nothing. I've traced all pipework for air leaks, I think that's as far as I've got...... Oh n new spark plugs. And no, no eml🙁
