If there is no change in voltage with the engine off versus the engine running, you’re probably looking at a failing alternator/voltage regulator. You won’t necessarily get a battery light on the instrument panel until the battery voltage gets low, which may be why it’s flickering instead of coming on and staying on.

If air can’t go through the air ports when needed, the engine may stall when you reach a stop or while the engine is idling. Locate the IAC around the throttle body. Unplug the IAC solenoid electrical connector.
