Are you sure you have carbureted and not fuel injected? Pretty close to year that they changed over I believe, if not 86-87

Yeah autozone shows the 318 as a FI engine, the 360 was still a carb.

I was told by a mechanic it was a 318. It has a two barrell carborator and three relays near the carb. This is a heavy duty truck with a creaper gear. Then it probably is a 360 engine.

Sorry guys,I got confused with my old truck, this is a Dodge Ram 100.
The owners manual talks about cleaning the choke shaft on the 5.9 L but says nothing about the 318.
The "thing" on top of the engine looks like a carburator, but it apparently is not. It has a throttle plate that moves with the accelerator cable. Above the throttle plate are a set of jets with wires going to each of them.
The truck runs lean when cold (can barely get it to move) but runs normal when hot.
Will dump fuel injector cleaner in and see what happens.

You more than likely have a faulty throttle body temperature sensor , or coolant temperature sensor. I'd go with throttle body temperature sensor first by sounds of it. They both (as well as other sensors in your vehicle) send info back to computer to inform it to send more or less fuel as needed. My guess maybe $10 for throttle body temp sensor, and $20 for coolant temp sensor.
