ok so just replaced my manifold gasket on sat and now more problems have occurred. Jeep idles fine but sputters when I 1st step on the gas. Another problem is sometimes it skips just randomly while driving. I did take off the fuel rail and injectors during this process. any advice?

 

I know it sounds obvious but make sure your injectors are nice and tight and did you retourqe the manifold bolts after alittle driving, if they are loose you wont have the right back preassure in your engine
