My wife has a 1.6 astra and i have noticed the fuel consumption is crap. I removed the induction kit and fitted a standard air box back on . This has nt made any difference. The car is standard , no big wheels and standard exhaust. Please help as its doin my head in ? What could i do to improve this and no suggestions of sellin the car lol . Would a service help ? Would disconnectin the battery for an hour to reset ecu after the ind kits been on Please help !!
