Ok, I still have this problem. It runs a little better until reaches
normal operating temp, it seems to bog down when the accelerator is
applied medium to hard. I have learned to back of the accelerator
just a bit and the hesitation goes away, as long as I apply the
accelerator slowly thereafter.
This is a constant problem and consistently hesitates when pulling a
hill due to the need to apply throttle more than on flat road. On a
flat road, I can slowly accelerate up to well over 100 mph and top end
seems good, but from low speeds, it's like the car is in top gear
(when it's not) and I'm trying to accelerate from 20 or 30 mph without
downshifting. Letting up on the accelerator just a bit, the car
springs to life and acceleration resumes but at a slower rate than if
I had full power. It's like there is a dead spot in the mid to high
range of the throttle pedal. New Throttle position sensor changed
nothing. No Codes. The only thing I have not changed is the Coils.
Would a bad coil cause this symptom?
