Last week (Tuesday) I was driving along and my traction light came on along with the emission light and the car died on me. The AA ran live diagnostics and showed the air mass sensor showing no air going into the engine. The sensor was unplugged so I could drive to a local motor factors to pick up a new one. I fitted the new sensor and all was well until saturday when the emission light has come back on and now the car feels a little under powered. I have fault codes to show AMM malfunction and fuel trim malfunction but I think this was from the origional sensor failure.
Any ideas? its a Z18XE
