Why does my A4 lack power
AUDI A4 QUATTRO B6
when i accelerate the car it seems like its lacking power, i push the acceleration pedal all the way to the floor and still no juice. the car slowly gets up to speed. i changed the Mass air flow sensor but still lack of acceleration power. i waste so much gas trying to keep up speed. please help!
Most frequently, a turbo problem - does it have a boost gauge? Automatic or manual?
Have you already checked for simple things like a dirty air filter, clogged fuel filter & pressure tested the fuel pump?
