I have a 2004 Jetta tdi wagon with about 80k. When accelerating at around 2k - 3k rpms there is some studdering acceleration. I thought it was the MAF replaced it and the studdering is still there.
Has anyone had or heard of the lift pump failing gradually? It seems like most people post that they were stranded. I can't think of what else this could be. It certainly seems like a fuel delivery issue. I replaced the fuel filter about 4k miles ago but maybe I'll just do it again. I run both dyno and bio. The problem is admittadly worse with the bio. It has been going on now for about 1,000 miles and has only gotten a little worse in that time. My car runs fine so long as you don't accelerate too much. I can get it to 80mph and beyond but the lack of power when you need it is getting frustrating.
Thanks
