Looking for some assistance. Suspect a fault with my DME here. Number 2 and number 4 cylinders not firing. Getting power to all coils. Found both coils to be leaking/burnt out. Fitted new ones but they're still not firing. >14v (with engine running) to both coils as with all the other cylinders, so no probs there. DME relay replaced to no avail.New spark plugs fitted and gapped.The 2 affected appeared a little burnt at the electrode also. The biggest head scratcher is that with my cracked carsoft it shows OK status when i carry out a scan on my DME. Not sure if thats down to my carsoft being a cracked Chinese import. Any assistance would be grately appreciated. DME is Siemens MS40. I think it'll need replaced. Any repair ideas? Please help!! Cheers..
