I have clean the throttle body valve with carburetor choke clean. Use the whole can in both injectors.Put a new rotor button and dist. cap on too.Replaced the 2of 3 valves around throttle body. The 1 facing the housing and the one to the left facing my left knee. Did good for a while, but still up to its' tricks the next morning.All the replace parts were the original parts. I am to believe the spark plugs are the same as well. Gonna change them next if if can get the wires off. They were too tough to remove Saturday past. -

Check fuel pressure first. This will put you in the right direction. If fuel pressure is too low, you may need to check fuel filter. Full Diagnostics needed past that so as not to throw parts at the truck blindly. Let us know if we can help further. -

Thank you for your reply sir. I have not checked the fuel pressure yet. I changed the sensor in front of the throttle body that faces the housing and I changed the sensor to the left that faces the driver side. Only the 1 in the front remains the same.I changed the Distr cap and rotor button. I notice if I leave the Bi Level switch on and turn fan to high,it didn't cut off when I stopped. Should I adjust the fuel flow or something? Not sure how to do that but I can learn if need too...I just wanna thank you for even taking the time out of your day to care about my situation sir....Thank you so much. -

Did you replace the idle air control valve? -
Answer 4
Is the battery in top shape because a battery that's on the way out can make it appear that electrical components are faulty .I have Dodge Ram too and when I had the same problem I took the air control motor out and cleaned it, but the battery was past its 3yr. life expectancy.After replacing the battery I wonder if that was the problem was a all along.Because the radio is so much brighter now.Before diagnosing anything it makes a lot of sense to have the battery load-tested or replace it, if it is near it's 3yr.end of life.The p.c.m. needs 5volts to function and everything is controlled by the p.c.m. -
