I currently have a 2016 chevy cruze LT. Recently I replaced my valve cover because it was leaking oil. When finished I tried to crank the cruze up and it sputtered a bit at first. I allowed it to just run for about 15 minutes then i decided to take it for a spin but notice it would not accelerate at all. I double checked to make sure everything was intact. The only thing I noticed is I couldn't find the little purple clip on the ignition coil connector. Is this the cause for the deceleration and where can I buy this part?
