First of all, no power up hills, slow to respond etc... ready to tear the whole engine apart, my son had put them damn red covers over his pedals, using a clamp- he left the end sticking out, gas pedal wouldn't go down all the way. didn't realize this until my 11 EEE foot got stuck and ripped off the pedal cover. Amazingly, lots of power since then. Trying to get 11 EEE out of his *** right now.

 

Slap your son upside the head call him a ricer and take the car away from him.

That should do it.
