Emissions, the gas throttle keeps racing high?

Hi,

When you say throttle keeps racing, do you mean the engine idle speed (RPMs) are high? If so, how high does it idle? Is the check engine light staying on when the engine is running?

As far as a high idle, it can be a few things. If the engine light stays on, have the computer scanned.

Here is a link that explains how to scan all modules:

Next, a higher idle can be caused by an engine vacuum leak.

Here is a link explaining how to locate and repair a leak:

Let me know if these things have already been done. Also, am I correct in saying the engine speed at idle is too high?

Let me know.

Take care,
