EML still flashing!!

[paulindor]

Now and again my engine managment light will flash, usually after its been sitting idling! I got it put on a computer and its showed fault 278 destructive missfire! i changed the spark plugs, leads and coil pack! it stayed off for a week then came on again when idling!

Anyone any other ideas? would a low battery cause this? if it was an injector it would show a fault on the computer i would think!

Thanks

Does it run ok on idle? OR run lumpy?

it would run a bit lumpy on idle?

The ECU is picking up a mis fire,try and work out which cylinder is causing the issue,you say you've replaced plugs,leads and coil pack,next step (if it's a single cylinder fault) is to change injectors.
