Check your fuse box in the engine compartment, look at fuse #25 to see if it is good, if not replace it.

The error code P0650 is a malfunction indicator lamp circuit, malfunction conditions. The possible causes are the MIL control circuit is open, or shorted ground to the system. It is possible that the PCM has failed, and it can either be flashed, or replaced. Remember to use genuine Delco products for optimal service.

Have 2002 rodeo lse...what is brand of stereo? Want to purchase new factory stereo...bought one previously, that looked like installed one, but did not work because of tuner or amp issue.

There were probably different stereo unit options available but the particular stock stereo in my 2002 Rodeo was a "Clarion" Model No. P1-9993M (cassette player). I've since upgraded to a better aftermarket head unit so you are welcome to my old one if willing to pay shipping (ha,ha).

Same issue with the rough idle with a warm engine 4.0 Ranger

i would think a plugged fuel injector on # 6 cylinder could be the problem,or a big vacuum leak at that cylinder
a valve burnt/stuck could be but you dont see much of that anymore
could be coolant leaking into cylinder from leaky haed gasket but you would have to add coolant every so often
i would check #6 cyl. spark plug after driveing around a while if it looks new, ie no deposits on it then an injector would be what i would change next
