If the engine idles that high in park or neutral, that is not normal.
The most common cause for this condition is a faulty throttle position sensor or air/vacuum leak.
Some other possible causes are a stuck throttle body, throttle plate, and a sticking throttle cable.
I would start by checking for air/vacuum leaks first and fixing or replacing any as needed and then checking the TPS and throttle body (sticking or stuck open for any reason).
Do you see my reply above?
Thank you for that information.
So this problem does or does not happen in drive while accelerating?
So it does not happen in drive right?
It is only in park or neutral?
And there is no codes in the computer and no check engine light illuminated?
Do you know what code was stored in the computer?
Ok, thank you for that information.
I would get that checked as your next step. If there is a lean or rich code, fuel trim code or converter code or even mass air flow sensor code, it might be contributing to this issue.
However, if not, then yes, I agree with the mechanic as this sounds like a rev limiter preventing the engine from accelerating too high.
I am glad I can help!
