I have 2000 A4 TA and i've noticed the past few days that if i am cruising around 30mph and i put the pedal to the metal it takes 3 to almost 4 seconds for the car to recognize that its wide open throttle and then it finally hauls ***. Its never been so slow to react before, why now? I haven't done any mods or anything like that. The only thing that i think might affect it would be the fuel injector cleaner i put in about 2 weeks ago ( but i don't see that doing anything). Do you guys have any ideas??
