When in Park my engine is fine until I reach 3000 RMP and then it starts to stumble like it is misfiring. What could it be?

This can be many things such as a broken valve spring bad spark plugs/wire/coil fuel injector, flat camshaft, can you scan the PCM for codes and let me know?

Hello Ken, I ran a diagnostics check and got no codes. It will be a few days before I can do anything else because I have to go into the hospital for some tests. I will get back to you as soon as I can. Thanks, Jim.
