04 plate 130 TDC - Lack of power - MoodyGit
My 38k Mondeo has just started having an intermittent problem. It looses power.
It runs but only revs very slowly - I just got out accelerated by a double decker bus!!

I've noticed that when this happens the temperature gauge also stops working. If I stop, switch off and then on again (rebooting it? :-) ) it revs OK.

I presume it's the engine management gubbins and it's due for a service in about another 1k miles or so, so I will mention it then. Just wondered what sort of cost it's likely to be

Or any confirmation what the cause is.


Thanks

Mark

It sounds as though it's dropping into "limp-home" when the ECU detects a serious fault.

There are many [thousands of] possible causes; but on these, injector issues are common.

Thanks for thr reply,

Is my usual garage likely to be able to track down the fault or should I go to a specialist?

Is 'limp-home' mode by design then? Or is that just what tends to happen, if you know what I mean.

It's a "safe-mode" strategy to protect the engine if a sensor fails.

If your garage has good diagnostic gear and someone who knows what it's telling him - then give them a try.

OK thanks

I've booked it in for a service and told them what the problem was and he said it probably needs code reading - sounds like they know the right words if nothing else! ;-)



Going to be an expensive week; our other car (an X reg Rover 25) is having service and MOT next week as well! *gulp*
