So the car was running a little rough tonight, and then I finally got a check engine light, and it would barely move from a standing start. When I would start off, it felt like it was running on 2 cylinders. Once up to about 2000 RPM or so, it smoothed out. So I drove home in 3rd gear. It just so happens I have an appointment for an oil change in the morning. Good timing. The car has Starmark warranty. Any ideas? I first thought MAF sensor, but I don't recall any of my VWs being rough when a MAF died, just slowwww.
