When I start my 91 camaro it runs fine and idles the way it should after it warms up a bit the car starts to idle ruff, once I put it into gear or turn on the A/C the car starts to idle very ruff and after a few seconds stalls out. I have tried new air filters, gas treatment and replacing the battery, there is a chip in the car right now that I got from a friend. What could be the problem that is causing this and what could be the solution, and how much might it cost

Do you
have the same problem?

First, get rid of the chip and go back to stock.

Check for vacuum leaks. It may be a hose broken or leaking

check fuel pressure.
