sensor underneath the pedal may be faulty, its a cheap fix, start with the easy stuff first and go from there

Easy fix for me... I had exact same problem and symptoms, ended up being water and corrosion at the connector to the ecu... cleaned up contacts plugged back in and no more issues... hope this helps

He needs to recalibrate the TB. Give me a few and I'll see if I can find a link to how to do it.

Here you go...... try this.

1. Turn the key in On position, do not start the engine.
2. Depress accelerator pedal and hold it fully depressed for 5 sec.
3. Turn the key in OFF position, while keeping pedal depressed. Do not remove the key.
4. Take your foot from the pedal, leave the key in for 2 minutes.
5. Remove the key.

This should reset Drive-by-wire (Accelerator+Throttle) adaptives.
