im struggling to get good mpg's in this rush hour city traffic. its not really stop start stuff its more like slow highway crawl uphill home. my drive to work is awesome I seem to have the longest daily coast on this forum

but that is too work. in the afternoon it is climbing back up the hills and im battling to get my little 1.4 below 6l per 100km (38mpg) on combined cycle. ive used all the tips on the forum but I am still struggling.
how will a problematic oxygen sensor effect this? the engine light was on for a while and a workshop diagnostic said a left bank oxygen sensor needed replacing. I borrowed a friends obd2 plug and cancelled the fault not replacing anything and now 2 months later the light has not re appeared.
however the car does not pull as well in the lower rpm as it use to it almost feels like a carb motor when its cold? could this be my problem? or is that just the figure I can expect from small engine in a quite heavy car?
