My Buick Century runs fine when it's at idle but when you put it in gear it wants to die out but will only stay running for a little bit if you keep holding the brake. I do not know what the problem is. If you have any suggestions, please let me know.

Has the check engine light come on? Have you checked fuel pump pressure, vacuul leaks?

Let me know.

The check engine light did come on but went off. I replaced the computer and no codes were thrown after that. It would run fine after that but there was no acceleration while in gear. It said it was running too lean so I replaced the M.A.P. Sensor and now it says it runs too rich. I'm running out of options

Have you checked the general things like the catylatic converter, fuel pump pressure?
