I have a 2004 ls engine. The fuel injectors are bearly in the Lower Intake Manifold (see pictures) My guess is the brackets that screw into the L.I.M. are bent... Am I right or is this normal? Please reply asap, I need this back together tonight.

 

Do your injectors look like this? Please take a second a reply.

 

Im worried because the p0300 code is coming up. Along with 1811, 0507 and 0420.
