high rpm power loss

[robortwillys]

Hi to all,

Okay.. Today I put in new engine mounts the car ran great before so once i finished i took the car out for a spin it started and ran well then once the oil warmed up i tried to rev the car out and it started spuddering around 5500ish the car will spudder sometimes but it will also run out correctly half the time it will always revup with the clutch in? LMK if you have any suggestions.
No vaccuum leaks relays are good i did some research and there is no play in the vibration dampener.
