Hey first post on the forum unfortunately not on the best terms. I apologize for the novel I’m about to post.
I have a 2012 Ram 1500 w/ Hemi. It’s got 116,000 miles on it and I took it to the dealer for the 100k service back in October.
Anyways I had the oil changed fully synthetic 7qts 5W-20 (normally I do it myself) prior to a short road trip. About a week later my CEL came on and I check the codes (have a diablo trinity installed) I got P0303 and P1524. So I replaced the coil pack in the third cylinder but not the spark plugs as they were changed less than 15k miles ago.
This resolved the issues for a couple days then P1524 came back on, followed shortly by P0303. Great. Replaced the oil pressure sensor and checked the oil level. Oil level is about 1/2 an inch above the safe zone but oil is clean, no foam, no smoke. Also it might be worth noting that the “oil change due” message on the display won’t go away even if I try the reset explained in the manual.
Idle oil pressure is ~20psi sometimes as low as 18. Cruising pressure is 30psi. Full throttle is ~45-50psi. Normal operation is smooth as ever under 4000 RPM. Whenever I floor it I get a choppy exhaust note and a rough reduced acceleration in high RPMs. Also I’ve noticed slightly lower gas mileage at times. Normal for me (with CAI) is 16-18mpg and I’ve been averaging 13 lately.
I reset the codes yesterday before work to see if they were related. Drove to and from work (80 miles) and no light. Driving to work this morning both P1524 and P0303 came back about 25 miles in while I was cruising and oil pressure showed about 28psi.
I’m trying to get a feel for what the problem might be before I take it into a mechanic and waste money paying him to diagnose it. Also I plan on trading the truck in within the next couple months so I’m not trying to undergo and major repairs. Any idea what the problem might be? Should I just drive easy and trade it in?
