What should the oil pressure be while idiling on my 2.2?

The oil pressure while idling on a 2.2-liter engine typically should be between 10 to 20 psi. However, this can vary slightly based on the specific engine model and the manufacturer's recommendations. It's essential to consult the owner's manual or a repair guide for the exact specifications for your engine. If you notice significantly lower pressure, it may indicate a problem that requires attention.
