Hi guys, (1500, 5.9L, Auto, 2WD, 136K miles)
Still having weirdness with the Ram, but have some more information. Starting from cold it is perfect, responsive and great to drive, cruise, overdrive-button and A/C work as expected.
After a perfect 20-mile run into town, park and shop for 30-minutes, come out and start and within a mile or so it is running rough. The A/C is permanently on no matter where the controls are set and the cruise and over-ride-button do not work.
A few miles later the Check Engine comes on. Checking codes they are a different bunch each time, usually four or more.
This morning instead of heading for town, I went the other way for 10-miles, turned around and drove into town and beyond, turned again and came back into town. Still perfect to drive after 60-miles. parked, turned it off for 5-minutes, started up and still prefect. Drove a a mile, parked for 15-minutes, this time on restart, rough running and all the maladies mentioned above. Idle is lumpy but mostly manages to stay alive.
Battery is good, load-tested by NAPA guys.
Fitted new terminals and soldered cable ends to all #6 and the other smaller wires to it.
I checked the temp of the PCM many times and always between 122-F and 124-F no matter if it was running well or not. Not the PCM overheating.
New distributor cap, rotor plugs and wires.
Checked Cam and crank position sensors, both good.
So, it is something that happens 15 minutes after driving, but before it cools down completely.
OK, gurus, where do I go from here. The great running from cold makes me want to keep at this it's not a scrap yard candidate yet.
