My car starts juddering in 1st and 2nd gear when releasing the clutch and also judders when accelerating in both these gears when going in between 2000 and 3000 revs. The management light comes on every now and then when this is happening. Any help would be appreciated.

If it's a judder rather than an engine misfire , I would check engine / gearbox mountings .If it's caused by a misfire , first thing I would check would be plugs and leads .To eliminate guessing , get it scanned for fault codes .

It had a full service when I first took it to the garage they thought it was because of the air filter was black. All spark plugs where changed and checked. Took it back to them and they got ford assistance and they told them it could be the battery or ecu. I changed the battery but still did the same thing could this not be an ecu problem?

I had a diagnostics check and they said there was no fault codes just a pending one of P0641 that why I think they where thinking ecu problem.

We had a similar fault on the other Ford forum I'm on and if I can remember correctly it was to do with a small wire in amongst a bunch going from the MAF sensor to the ECU , worth a look .

Car still doing the same thing took back to the garage and had the ecu tested and that's fine. They need to wait for it to come back before deciding what to do next. Can the coil pack or maf sensor cause problems but not show up on a diagnostics test? I'm not really good with cars.
