Good morning Scotty, hope you're doing well. Maybe you can help me out I bought a 96 Acura RL with around 255000 miles on it. I replaced the spark plugs started to have a misfire in one of my cylinders. When I changed the plugs I noticed oil in one of the spark plug wells .so I cleaned it out amd changed valve cover gasket and plug o-rings and put a new coil pack as well since I rip the boot. Ever since finishing these repairs I've had pretty poor performance. I disconnected the battery for an extended period of time so I follow procedure for Honda/ Acura idle relearn. My car was more peppy after this but I still can't rev over 3000 RPMs I also have a really hard time taking off from a full stop. However once I get up to speed there's no problem at all . I can drive at highway speeds all day long . At this point I don't have a check engine light so I don't know where to go from here. Thanks for reading hope to hear back from you soon.

adjust the valves on the engine and do this cleaning video and pray that helps https://www.youtube.com/watch?v=cP7D-5iQcNo
