- 2009 Explorer 4.6 3v V8
Hello
I have a ford explorer 2009 4.6 V8 3v
When I'm driving between ~25-60 mph, with ~1300-1500 rpm, and I try to light accelerate, there are noises like Grrrr instant knocks and the car is vibrate
I looked on the rpm and it seems that during this noises, the rpm jumps to ~1700-1800 rpm and drop back to ~1300-1500rpm.
It's feels like it getting difficult to accelerate at this velocity with these rpms.
If I try to accelerate with 2000rpm or above, there are no noises and vibrations.
During the acceleration from 0-25mph, or above 60mph, the car drives smoothly.
Is anyone experienced with this phenomena?
What could be the cause?
Thanks
Guy
