04 ram 1500 5.7 misfire
04 ram 1500 5.7 hemi
174000 miles
New parts ive just recently installed:
Radiator. Water pump & thermost. Ps pump & cooler. Coolant control temp.
Recently got out of the army and needed a vehicle so i decided to buy my dads dodge as he is currently deployed overseas and wants a new truck once he returns home. It sat about 1.5 to 2 months between him leaving and me buying it. Had a more mechanical savvy friend look it over for me and recommended some parts to be replaced, which i listed above. Then it started misfiring with a p0300 code. Recommended the coolant temp sensor be changed so i did and the misfire went away but 24 hours later the misfire returned. After research and learning it could be a list of many many things causing the misfire I just decided to do the spark plugs. Found one was cracked so i replaced it. Cleaned the others and regapped them. I know, i should have replaced all of them but i have not had income for a bit now and cant replace them til i start work. Anyways i put the plugs back in and everything, started it up and drove around and no more misfire. Drove around an hour or so later that evening no issues. Engine sounded great amd smooth. Went to go onto town this morning and after 6-8 minutes of driving the misfire came back, along with the same p0300 code.
So does anyone know why the misfire and code go away after those repairs but return the next day? Also have codes for 02 sensors. P0152 and p0038 i believe.

Another thing thay just clicked today..i realized that when ive replaced the parts the 2-3 different times ive obviously unplugged the battery and when i get done with everything and plug the battery back in and then start it and let it run and get up to temp theres no misfire. So then i always drive it after and usually for about 30 minutes each time. The misfire stays away for maybe 12-15 hours then it comes back. So maybe something to do with the ECU? Or sensors maybe? I cant seem to find anything online about it. Also thanks i will start that p0152 in the morning then
