Q: My 2006 F150 FX4 5.4 with 112,500 miles seems to like to hang up at 2000rpm. it accelerates fine up until that point

asked by on

seems to like to hang up around 2000rpm. it accelerates fine up until that point, with good power. once it hits ~2000 rpm it seems to lose power and really won't go any higher. It will rev higher than 2000 if i accelerate hard enough to downshift but it still feels low on power when it does.

I have replaced fuel filter, spark plugs and cleaned the MAF and throttle body.

My car has 112500 miles.
My car has an automatic transmission.

Hi there. Generally speaking, when an engine is idling high as you’ve indicated, it’s caused by either a faulty idle control valve, damaged throttle body or vacuum leak. It’s always best to have a professional mechanic complete an engine idle inspection to determine why you are having this problem and recommend the right repairs.

Q: The driver side power window will not roll back up

The most common cause of the window will not roll up is caused by the window regulator binding up causing the motor to bind. I would recommend having the motor and regulator checked and replace motor and regulator.
