[QUOTE="bimmer73, post: 341120, member: 1666"] Ok I have tried running the car without the MAF the engine was much lighter. The readin on idle fro the MAF sensor was 13kg and when snap open fast it goes up to about 70k - 250kg. My mechnanic decided to try changing my EML unit under the trottle body and the car is much better and the fuel consumption is stable. I will run with t for a few day an see what happens. so far no sign of engine check on. Funfer I have already removed my ECU but the same thing happens a few hours later. Anyways will update in a day or 2 with the latest outcome. [/QUOTE]
