Maintenance/Repairs

i replaced the maf , spark plugs , catalytic converters ,1 of the coils.my car would not go over 2000rpms until i did all that work.now it wont go ovef 4000rpms,it gets stuck and wont go any higher even if i slam the pedal.it also has a misfire and sqeuls when i start it until it gets a little bit warm.it has poor accelaration from dead stop.but it sometimes runs pretty good,ill be able to slam the gas & it will fly and be fast as hell,but most of the time it runs bad.cam anyone tell me what this is?
