Hello guys, I’ve got a really nice problem. I drive a Mondeo Built February 96 with the 1.6l 16V machine.For some time now my engine has been running unevenly.In addition, it consumes 13.5 l on 100km with economical driving and the values of the AU are far from good and evil. It runs far too fat. Before it ran like a clockwork.Hab driven it with 8l. We have already made the vacuum hoses, the ignition cables, the spark plugs, seal from the Khrümer to the Kat. New Lambda probe and new air mass The values are still bad. I brought him to Ford a few days ago with the task to find the fault. There it was said, the engine and all the attachments are in order. He was also connected to testers. After a calculation of 100€ I was told that it was possible to find the cat. This is to be used and thus the exhaust gases are to be stored. I was advised to blow it out nicely on the track once. Said done.Now he runs to the track. auso sch. as before, if not worse. Do you have any advice? I already put a lot of money into the thing and so slowly I don’t like it anymore. Games with the idea to sell it.
