The oil you are now using is completely fine with that type of engine.
Changing grades of oil will not help you here.
You need to check the PCV valve, and the MAF sensor.
Really you need to get this vehicle onto a diagnostic computer to get an idea what is wrong.

10W30 should be fine... not sure if you know what those numbers mean... basically cold it will be 10 weight when it warms up 30 weight.... in cold climates that's important for starting the motor.

Oil used in a 1992 Isuzu Rodeo


depends on your temperature, and where you live if it uses a little oil use a little heavier to cut consumption. If it is always cold where you live like below zero, I wouldn't use more than a 20w 30w. in warm climates a 30 weight oil is ok, but if you have low oil pressure you can safely use forty weight.
