306 emissions (overfueling?)
Hi, did a search couldnt find anything about this.
Im trying to get my 1.4 '97 306 through its MOT but its failing on the emmissions.
For the MOT ive just changed the Lambda sensor and Cat and its recently had a new coil pack, air filter and plugs and leads.
The exhaust doesnt seem to have any leaks and my mechanic has cleaned off all the sensors.
During the test it needs to be revved a bit to get the co2 level down but after that it does fine on the fast idle test it sits at 0.0. As soon as you take the foot off the accelerator for the idle test the co2 shoots up and it fails at about 1.83 on average.
When im driving it, also, if i slow down for a corner and change down a gear it sometimes backfires.
The plugs get pretty sooty too!
Bloody cars costing me a fortune! :mad:
