After about 2 minutes of driving my 58 plate mk 7 fiesta looses power when i'm cruising at a steady speed. It only kicks in again after the revs drop below 2000 or if I fully press down the gas pedal to the floor. Any idea whats wrong? Ste.

Hi, i have had something like this, and it turned out to be the lambda sensor, get it to a ford dealer and get them to check for fault codes, and also to monitor the pre cat lambda sensor via datalogger to see if its working correctly, the vehicle i had was from another garage that couldn't find the fault, and took me a while to find it too!
If it is the sensor, i will warn you that the sensor rots into the manifold, i ended up taking the manifold off the one i had to remove it.
