I replaced the old style injectors with the new style oem 370cc injectors used in the 95+ tt model from z1motorsports. Yea I lubed them exactly like it was said in the instructions and they sat nicely on the fuel rail with the adapter kit for my z..that explains why acceleration is not smooth and I feel a loss of power if I'm running on 5 cylinders only. I installed a brand new ptu sensor since the car didn't want to start at first After the plenum pull/injector replacement, dealer did timing belt 1 month ago, brand new spark plugs,injectors...so I'm stuck
