My car starts but doesn't idle. Unless you have foot on gas, it shuts off. Garage at first thought it had to do with air system; then called back and said I need a new computer. Anyone else have this problem? How much is a new computer?

I would get a second opinion, idle is controlled by the IAC (idle air control) valve.

It may need to be replaced or cleaned. While PCM is a possibility (remote) it sounds more like a way to get extra money from you.

New or remanufactured PCM can run anywhere from $500-1500.
