I have an Audi TT 1.8T 2001 with the 180hp engine. I have been having a problem where if I am at about 2000 rpms or so in 3rd or 4th gear and sometimes 5th gear and I just nurse the gas and not give it too much the car stutters. Once I get to about 2250 and above the car picks up just fine, but that stutter really has me worrying. I have no check engine light on currently at all. I'm thinking though, that it's possibly a MAF sensor problem. Anyone have any ideas as to what may cause this? Thank you in advance for you help, you guys have always been a killer resource!
