Awesome! Hope you get it sorted out. These stupid little problems make it difficult to enjoy the car. I have a ceramic disk which replaced the street disk that welded to the flywheel last weekend. Prior to that, I've been dealing with shifting problems due to the disk dragging with the flywheel. After bleeding all the air out of the lines, the car is such a joy to drive. Pedal travel is tight (no floppiness from initial travel) and easy to modulate, perfect engagement point, etc. Gear shifts are so smooth and light. However, 3rd gear wants to grind above 3k RPM after driving for awhile regardless of load. Hopefully it's just an adjustment issue

I appreciate the input, it helps to narrow down the options I have to take.

Honestly no experience, but I read about some users who had the annoying rev limit and CEL and later was diagnosed as faulty CAS or MAF. I do have an UpRev tune with no major issues. Every once in awhile there's a rough start as if there's too long of a delay between the fuel pump running to starting the engine.

going try running a colder plug then looking into the coil packs first. since it goes away if you restart the car it looks like it may be tripping the sensor

not sure? do you have any experience with this. where is this sensor located. plus I get bank to rich with codes along with the misfire codes as well. looks like this may be the main cause.

I saw your post about your car going limp. Can it be the cam angle sensor?
