Engine revving higher,usual operations,gas pedal not engaged.?

That is possible. Let me know if you have additional problems of questions.

Thank you! I was doing more research and throttle censor kept being mentioned but thanks for the pointer.

No aftermarket parts

Post codes. Monitor Idle air control valve , that is more likely than TPS to cause high erratic idle. Check coolant level.

Thanks my friend. You have been very helpful.

If you post code(s) may be of more help.....
