Ive had my 2002 307 for 3 years and had plenty of Antipollution eppisodes. Firstly the CAT which was replaced and the slugish performence was cured. A year later, the famous 307 dreaded missfire starts, 5miles down the road from start up in the morning. I had a coil pack fitted which it cured, but the Peugeot Guy said it could or next be the injectors.
Well ive had the Anti-Polluntion light on for months now and no problems even when i get it switch off it returns but no problems.
Untill today the missfire has started, RAC cant find the missfire now the car has been stood, but said it could be your coil, i told him ive had a coil a year ago, so im back to square one, only guessing its injectors but the cars is ok at the moment but dont want to drive it anywhere just incase.
