I’ve recently bought my challenger in October I’ve done tons of work including tune up map sensor throttle body purge valve pcv valve and tube and it has this rpm fluctuates not a whole lot maybe a hair back and forth sometimes it does it and sometimes it don’t and it also jumps when going into second sometimes not all the time it has slowly got better by replacing the things I’ve listed up above I do have to replace my oil cooler when I replaced the pcv valve it was busted so oil got into my intake and etc didn’t clean it out don’t know if it has anything to do with it the spark plugs didn’t have oil on it but I’m at a stand still don’t know what it could be it also still has a miss and it also shifts really good to be the transmission it only has 105,000 miles

It sounds like you have already replaced a lot of components that could be suspected culprits. If oil got into the intake, it might have coated the mass airflow (MAF) sensor, which could cause inconsistent readings. Cleaning the MAF would be a quick step that could help. A vacuum leak or fuel delivery issue could also cause the miss and hesitation, especially if it’s worse under load like turning or going uphill. Since the shifting issue is intermittent, checking for transmission codes and fluid level and condition might be a good idea too.
