Cam position sensor

Grab a can of carb cleaner and spray all around the intake, throttle body, etc. Also, rent a fuel pressure tester and see what your pressure is at idle and when you crack the gas open good and hard. Should jump to about 62. See if it leaks down right when you shut it off too.

By crack the gass open you mean open up the throttle right?

Check the dizzy button for play. Could be a worn distributor gear, happened to mine a few years ago. Same code, along with not wanting to start when hot and mild loping sometimes. I didn't figure it out till the gear was chewed all the way thru and my engine quit out on a highway.

Check the wiring continuity between the distributor and the pcm before replacing the sensor.

How would I do that, I have a multimeter, I'm just not great with electrical stuff so I'm trying to learn

Set the multimeter to measure resistance (the Ω symbol). Test the continuity by putting on probe on a the sensor plug and the other on the corresponding plug by the ecu. Repeat for each wire. It should beep at you if it's got a speaker or show a low number. If it shows no change on the screen it means you got a broken wire.
