ive got a miss fire problem on my zetec turbo, its running on emerald management and the engine and loom etc is all new, my problem is i have a miss fire on cylinders 2/3, i have a strong spark on all 4 cylinders, i have compression and i've noid tested the injector harness and all are good on all 4 cylinders, i then put 12v to the injectors of cylinders 2/3 both click, so i assumed they were blocked? so last night i removed them and put 12v to them to open them and blew them through as ahmed bajoo said.
Today i put it back together, started it up and problems still there, any suggestions of things to try? can injectors just bugger up? any help MUCH appreciated, thank you
