I have replaced power steering unit on my 00 fiat punto two months ago and its gone again during the latest cold spell. Is it possible that the ecu could b causing the problem as I have since got the engin warning coming on as soon as the car heats up in the mornings and I am then loosing power. If i let the car sit for a few hours and start again its the same problemonce it warms up.
