My car is accelerating slowly and loud. It'll get to whatever speed I need but it takes a while.
Once I let go of the accelerator it's back to being quiet instantly.
Sounds like you have not tuned this car up in a while. Start by changing yor air filter and gas filter. If no change change spark plugs, wires and pvc valve.
