Nissan patrol gq y60 engine is rb30 1991 carby on gas/petrol.
When the car has been driven and comes to a warmed up idol its either trying to stall or revving at about 1200rpm,
Stop the engine for 1-5 mins and when I start it again it idols fine untill I drive it again then the issue comes back,
Also its cranking over for a while before it will start first thing in the morning.
I've cleaned the distributor cap as it was gunky, replaced spark plugs, checked for any broken wires found non,
I'm not sure what the issue could be or how to fix it.
Any advice would be greatly appreciated.
