Hello all,

  Just Bought the car and noticed when in Drive4 and accelerated after about 10 min of driving the car would vibrate but only when I depressed the gas. I bought a new Fuel Filter because the car has 122,000 miles on it, and it needed a new one. That took a lot of the vibration away. Now it seems that the fuel going through the original filter would have been dirty therfore putting dirty fuel through the injectors? I used some fuel injector cleaner with a full tank of gas, a little improvement. Another interesting point, when I put the car into Drive3 it has no vibration at all. It runs smooth. What is the problem here? Transmission? Do I need some new injectors? By the way what is the best fuel injector cleaner?

Thank you for taking the time to read.
