Had flashing Engine management light come on last night, flashing intermittent at first and then solid orange warning I put it in the garage this morning and was told that the ECU reported an engine miss-fire on cylinders 1-2-3 and 4!! Anyone else had this before or have any idea what this could be the result of? I'm discounting all four coil packs going at the same time and they checked for continuity.
Connecter multiplug to coil pack distribution itself.
Fuel injection relay in front of battery connections often throws up a a similar issue that the ECU mis-diagnoses as a misfire, worth removing cleaning and re-fitting
a fairly loose negative connection to battery can give an intermittent issue too
