Good call Tulsa,
XFireCrazy,
The rpm drop is normal with shift to higher gear.
When you put car in park, they can roll a slight amount.
Welcome to the forum!
Great people, with lots of info
Here is throttle reset procedure
1. Get in your car
2. Turn the key to the on (not start) position, the position just before the starter
turns over.
3. Press the gas pedal to the floor with the key in the "on" position.
4. Hold the pedal to the floor for five seconds, then turn the key back
to the "off" position (don't remove the key), then release the gas
pedal.
5. Wait 2 mins. for a full alignment.
6. Drive the car as you always do.
It is not hard to do this, just follow the instructions -
Key on, pedal down, 5 sec, key off pedal up, wait 2 minutes.
Keep the key in for the entire thing.
