What Rpm Should a 5.3 Idle at

A properly functioning 5.3 should idle at around 700 rpm. If your 5.3 is idling higher than that, there are a few things you can check. First, make sure the throttle body is clean and free of debris.

Next, check the air filter to ensure it isn’t dirty or clogged. Finally, check the idle control valve to see if it is working properly. If all of these things check out and the problem persists, then you may need to take it to a mechanic for further diagnosis.

If your 5.3 is idling below 600 rpm, there are a few potential causes. A dirty air filter, low oil level, or blockage in the exhaust system can all cause low engine idle speed. If you’ve ruled out those issues, it’s possible that your throttle body needs to be cleaned or adjusted.
