Still powerless and high fuel com

[perryyip73]

I recently did changed my air valve. According to M1, they said it was licking and cause the lost power and high fuel comsumption and found nothing error when diagnostic. But last friday i went to Ipoh and tested full tank only can go 390 +- (city + highway). The speed i drive is 110-120km never slam on the accelerator. You can imagine im kind of driving like an old man. So far i did compared to E46 1.9 same as mine installed 18", and 1.9 is much more power and better fuel comsumption than mine. Im really lost on this. Hope someone can help out.2.0 E46Japan spec6 cyclinderyear manufactured 200118" wheel.everysingle thing is running well and still new condition.Perry 012-2383871 thanks.

The 320i 6 cylinder will consume more fuel than the 4 cylinder 1.9 that you tested. It probably felt more powerful as it has higher gear ratios.

Btw, the 320i has the highest fuel consumption in the e46 model range.

Try changing your cam sensor and clean out you Mass Air-Flow sensor, even if there are no faults with it.

Good luck.

Try check the vacume hose under the the top engine cover, ori is rubber type and change mine once the fuel comsumption improve immediate.
