I own a 97 Passat TDI with 102k miles. The other day I notcied that right around 3000RPMs and on there are 2-3 hesitations in the engine.Also, sometimes when starting out in 1st gear the car does not go through the gear smoothly. I get a bouncing effect, which is quite annoying. The car is completely stock and maintained well. I use fuel treatment every time I fill up too. I'm not really too sure of what could be wrong with it, but if someone has an idea or advice it would be appreciated.
