Hey all, I’m hoping some one can shed some light on where to go with this, my daughters car, 2002 1.4 auto …..failed it’s last mot on emissions, took the week to try sort it, added some forte to the fuel and had a good run in it, it’s got 3 faults keep coming back after obd reset, I’ve cleaned out the MAP & EGR just for cause, since then I’ve ran the obd diagnostic emissions tester and it’s passed them all but keeps throwing the faults up. Any guidance on what to do next? I’m thinking of replacing the lambda sensor in the down pipe Cat, suppose I’m just hoping someone else has had something like this! I’m changing the oil and filter today, the plugs are pretty clean and set right. Fingers crossed one of you guys can help me sort this without too much trouble 🤞🏼
