Backfiring.... no longer

(1/1)

Bluebottle:
Now I've got your attention!

My 3.5 EFI is misbehaving. it ticks over and drives at a constant speed perfectly happily but if you try and move the throttle suddenly it starts misfiring and occasionly lets off a backfire. Blipping the throttle settles it down again. It also doesn't like revving beyond 2700 or so, it misfires if you try it. I can't find anything obviously amiss under the bonnet, any clues would be welcome.

fatusbloke:
Sounds like could be air-flow meter fault or coil breaking down,
 I'd try coil first, and do usual checks on ign system plugs leads etc
 :)

Bluebottle:
Air flow meter seems to be the culprit, that's the majority opinion of people I've asked.

Ok, thanks for the response, I'll have a good look later today.

Bluebottle:
This was the problem, it was earthing to the dizzy.
