Engine management light came on suddenly and sounds like it's missing can you help please


Hopefully i can help..

Restarting the engine after the EML has appeared is only reseting the ecu fault memory until such time the ecu sees the fault again and thus each time logs a fault code(s) these engine can tend to have issues with there ignition systems..either be it faulty sparkplugs not original - ignition coil/HT leads faults - it should be possible to a balance test on the engine in by a way of engine running at idle - unplugging/replugged back in each lead one at a time to eliminate the mis fire. if one of the 6 leads is pulled and the engine balances out then you found the faulty cylinder..then its simple case of checking/testing that cylinder to find out if its ignition system related/fuel injector related/or compression problem/or possible inlet manifold leak..however make carefull checks around the engine and ensure nothing has driffted off electrical plug wise just to be sure - the next ideal step i would advise first even seeing as the engine light is continually flagging up in which really any garage/mobile mechanic would do this first is to get the fault by a way of diagnostically testing the car plugged in..and see what faults codes you have and with those check accordingly..its usually best cost effective way first..I do hope this helps..if you need to ask anything else or include anything further then just continue before you rate
