Ford Fiesta loses power and then jolts back in again

Car: Ford Fiesta
Variant: 1.6 petrol zetec
Model Year: 2006

Categories: Electrics, ECU, Warnings & LightsRunning Rough, Starting & Power Loss

When it decelerates the car loses all power even the power steering goes which is alarming all the instrument lights come on. When the car is at a stop you can turn the key to off then turn the ignition on again and it is ok to drive. I have taken it to a garage but the diagnostic isn’t picking up any fault codes.

You're losing the power steering because the engine is cutting out . Either try cleaning the idle air control valve or replace if needed , clean throttle body . Similar to this

Relatively minor job to replace IAC but worth tying to clean as it is often all that is needed .
