Hello everyone, I recently bought a 2001 is300 and it came with a misfire from cylinder 1 from the codes I ran. It is also leaking oil on the header exhaust side and I can’t imagine how bad the middle of the cam covers are (probably flooded). She runs fine but kinda late on throttle response and weak acceleration. I am planning on replacing valve cover gaskets and while I was there I was gonna go ahead and replace ignition coils,spark plugs and wires, and throttle body mounting gasket. Lmk if you can recommend doing something while I’m there and ANY tips at all would be greatly appreciated. THANK Y’ALL.
