DodgeaWrench Posted October 17 Report Share Posted October 17 Driving first thing this morning, after about a mile, I feel a slight missing occurring. For another mile, I wasn't sure if it was road bumps or engine. Then it got worse... No doubt... The engine was missing / running rough, and continued to get worse. The check engine light started flashing. The engine stalled when I came to a red light, but restarted. Stalled again turning into a parking lot, but again restarted. I stopped to read the codes ( I carry an ODBII reader), restarted, turned around, and said a prayer to hope to get home without a tow. The car is now in limp mode and I cant exceed 25mph. I slowly and safely make it the few miles home. On parking the car, the exhaust smelled (fuel) rich. CODES: P000D - Camshaft Position Slow Response Bank 2 P0018 - Crankshaft Position - Camshaft Position Correlation Bank 2 Sensor A P0175 - System Too Rich Bank 2 P0300 - Random/Multiple Cylinder Misfire Detected I spent time with my friend, YouTube, researching how the check, test, and evaluate, this series of codes. To cut to the chase, at least one of the videos had a checklist with CHECK THE OIL LEVEL / OIL QUALITY at the top of the list, and to start with an oil change. I checked the level and I was over a quart low. I was due anyway for a change, so I changed the oil / filter, and crossed my fingers. On measuring the oil drained, I was down almost 2 quarts. WTF! Putting the car onto the ramps before the change, it continued to run like 💩. After the change, smooooooooth. I then reset the codes and check engine light went off. Took it for a several mile spin, and no issues, no codes, no check engine. I'm in disbelief and still can't accept that a low oil level would create this type of issue. I've got places to go (drive) tomorrow and will be a good confirmation of the repair. I'll report back. Anyone experience similar? 2014 DJ 3.6 FWD 176674 miles 7k miles since previous oil change 6 quarts and filter used on this change Regardless of successful repair or not, the next question is what happened to the oil? There are no leaks. I definitely will be checking the oil level more regularly now. Quote Link to comment Share on other sites More sharing options...
Dean H Posted October 18 Report Share Posted October 18 A cars fluids is something you should check regularly. The more often you do. The more problems you will prevent or catch before it gets expensive to fix. The 3.6 is a highly complex engine internally. With it's wide engine RPM band. Your going to use oil. The harder you drive it even more so. With the 3.6 you should be checking the engine fluids once a week. It has a maze of heater hoses to watch as well. The 3.6 liter (219.7 CID) flexible fuel V-6 engine features Variable Valve Timing (VVT), Dual Overhead Camshafts (DOHC) and a high-pressure die-cast aluminum cylinder block with steel liners in a 60° configuration. The 3.6 liter engine has a chain driven variable discharge oil pump with a two-stage pressure regulator for improved fuel economy. The exhaust manifolds are integrated into the cylinder heads for reduced weight. This a view of the complex timing chain on the 3.6. This a cylinder head with the valve cover removed. The 3.6 has 2 cylinder heads. Picture the engine spinning up to 5-6,000 RPM's. You got damn lucky in my opinion. Quote Link to comment Share on other sites More sharing options...
DodgeaWrench Posted October 27 Author Report Share Posted October 27 To follow-up, it's been a week and the DJ has been running normal since the oil change (to replenish the low oil level). I'm calling this fixed. The oil level between changes has never been an issue before. I'll have to monitor it more often to determine if something else is a miss or if it's just getting up there in miles and starting to burn a little oil.

John/Horace Posted October 28 Report Share Posted October 28 (edited) Two quarts is not a little. Maybe last change it was under filled. The plastic oil cooler/filter assembly is know to leak oil if the seals start to fail. Watch closely where it is parked for signs of oil on the ground. With the beauty cover removed shine a light down into the valley right at base of oil filter. Shouldn’t be more than a few drops of oil down there, investigate if there is a puddle starting to form. Common failure item on the 3.6 engine. Some people switch to all metal assembly. Edited October 28 by John/Horace Quote Link to comment Share on other sites More sharing options...
