when I try to floor it, my car goes but studders like a little jerky like power is cutting in and out almost feels like clutch is slipping or like a fuel injector is spraying then not spraying then spraying then not spraying. I replaced the fuel rail so I have a feeling that its the clutch. Also It dosent want to go past 3 grand in fith gear and it takes FOREVER to get to four grand from 3. If I drive for a hour like this when I go to stop and accelerate again 1st threw 5th will bring me no where and I litterly accelerate at a snails pace. when I get off the interstate for some erason my car is fine again in 1st threw 4th but still I feel like an overall loss of performance and I can feel a little clutch movment from under the floor of my feet next to the tranny sometimes but not all the time when driving. Can a clutch simulate something like that? literaly feels like car wants to go but will jerk a little bit when florred like the cltuch is trying to grab but lets go and trys again ect like its slipping.
