(Sorry it’s so long, but wanted to describe) So i have a 2003 ram 1500 4.7 with the 545RFE with 217k
i drove thru a huge body of water (had no other choice) after she started acting up and then died! I did my research and checked everything and started replacing! Since i have replace the plugs, coil packs, TPS, tps wire harness, MAP, oil pressure sensor, cam sensor, serpentine belt, air filter, changed oil multiple times! I got her running beautifully except now there was a intermittent hard shift from 2-3 gear! Recently i was on a road trip when i went to start her up (in the cold) she warmed up and thru a misfire in 5th cylinder code! Now given how cold it was i knew this could be a possibility since she dove the 1st 1,000 miles beautifully and hadn’t ran since we got there. After getting warm i let her sit (around 30 min) and code was gone and she was great. I heard this loud tick about 400 miles into my journey home! I pulled over to fill up and check her out when i heard the tick a little louder! Checked oil she was a little low, when i opened cap to top her off there was like a yellow foam visible? I couldn’t stop i got her home. Now the motor whines and knocks and seems like my tps is fried because of idle and rpm movement. Any help is greatly appreciated
