So, I took my upper and lower plenums and manifold off to clean them. In order to pull the manifold off I had to disconnect the fuel injector harnesses and fuel rails. The check engine light has come on after I reassembled the induction parts ad started it up.

What do you guys think? Could it be a bad gasket, incorrect torque o a bolt or something wrong with injection system? Any help is greatly appreciated!

 

pull the codes it could be a number if things. be sure to check all of the tubes you pulled off, to see if you didnt connect or whatnot.

 

Well checked all the hoses and connectors and they are all attached. I'm worried that it might be a fuel injector.
