I did a search, but everyone has modded Focuses it seems. My '02 ZX3 has developed this problem where it sort of lurches or stutters when I am trying to hold a constant speed in 2nd, 3rd, or 4th at somewhere between 2500 and 4500 rpm. It doesn't seem to happen at highway speeds or when accelerating.
I tried some Castrol fuel system or injector cleaner, and it almost seemed liked it helped initially, but now it's back after about 100 miles or so.
The car has about 32,000 miles, and is still under warranty, but I know that the dealership will just say that they didn't notice it. What could be wrong? What can I do?
