OK, so I reckon there's a few knowledgeable types on here who like a challenge.
I bought a Mondeo TDCi to replace my Focus, which was... tired.
All was well and good until Wednesday, when an intermittent fault raised it's ugly head.
After driving for 20 mins or so, when I pull up to a junction or lights, the car appears to go into a limp-mode like state when I pull away. By this I mean that the revs rise really slowly, even with full throttle. The car is still drivable, but acceleration is... not very.
This state continues until the ignition is turned off, and upon restarting everything is fine... for a bit.
This loss of power has only so far occurred after stopping the car at a junction or similar, and not whilst driving in gear.
No error codes have been registered in the PCM, as far as I am told by the mechanic who looked at it, who is also baffled.
Does anyone have any ideas? I have a hunch about the clutch position sensor, but I havent been able to check yet.
