Default Major hesitation, slow acceleration. Won't rev past 5500.
So far I have done the plugs, wires, coils, solenoids and MAF. I bought this car last year. It ran fine. I don't know if the previous owners premixed and I don't know if the cat has the material in it. I have not had a compression check done. Any ideas?

It helps to post the year and exact model trim and miles when asking for service help
