The engine stalls sometimes when at slow idle or when turning slow like in a parking lot. i just replaced the plugs (ac delco) and wires. And it still sometimes does it.

HI there,

Thank you for the donation,

There is no adjustment for the idle speed, it is controlled by the engine management system, often poor idle control is the assault of vacuum leaks, dirty throttle plate or dirty or faulty idle control motor, check these first and repost if you still have problems.
