Hi folks, i have a very annoying problem that hopefully someone can help me get rid of. I own a '97 P A3 1.8 20V sport, non turbo. At about 2500-3000 revs theres a very notceable flat spot, i have tried plugging in the diagnostic machine at my work but it didnt bring up any faults. I have also been told it is the MAF sensor but want to be sure before i go out and buy one. My mates car with exact same engine has exact same problem!!!! Any help greatly appreciated
