Rough idle and no power after replacing the throttle body?

Hi,

If it is idling rough, are you sure there isn't an engine vacuum leak? It could be at the throttle body or one of the hoses may have been left off.

Here is a link that shows how to locate a vacuum leak:

That is the first thing I would recommend looking for. Also, let me know if the check engine light is staying on when the engine is running. If it is, then have the computer scanned for codes. Here is a quick video showing how it's done:

I realize most people don't own a scanner, but oftentimes a parts store will do it free of charge.

Let me know what you find or if you have other questions.

Take care and God Bless,

Joe
