I have a 2002 1.4 Auto Lupo which I am having problems with. Driving along as per normal, the engine management and the emissions light comes on, the car goes into limp mode and when I move gear selector into neutral it produces a hefty slam. I can turn off the ignition and leave the car for an hour, go back to it and it is back to normal and will drive normally bur the warning lights stay on for a day or two. I have had a new throttle body fitted,but after a week or so the problem has returned. Can anyone please advise me as to what the problem is as it is a lovely car and with very low mileage for the year.
