When attempting to accelerate, usually below 3000 rpm's but not always, I experience a hesitation/loss of power. I have found that if I back off of the gas a little, the hesitation usually goes away but then I am left accelerating very slowely or not at all. The problem is worse when climbing hills and has occurred even when the rpm's are above 3000. The problem seems to be worse when the engine is warmed up and occurs more often when the car is in 1st, 2nd, and 3rd gears. I recently put some STP fuel injector cleaner through it and then changed the oil and there was no change. The problem is somewhat intermittent.
