hi, i have a 2001 alfa romeo 156, about 6 weeks back i accelerated hard at a junction, the car just jolted as if id slammed the brakes on, the injector light or engine management light came on and stayed on! the car struggles to pull away as if its going to stall, took it 2 a garage, the diagnostic machine said it was the mass air flow sensor so i had it replaced, the lights now gone off but the car is still struggling to pull away as if its going to stall and the fumes from the car seem to smell stronger! ive reset the ecu but that hasnt worked! i have no idea wot else it could be, i had it serviced bout 3mnths back, you know the usual, spark plug change the full works etc so it cant be the plugs, the warning light looks like an injector.. but i have absolutely no idea what it could be, sum1 please help me out the car is stressin me people lol! cheers!
