I just replace my injectors too. Did you replace the o-rings on the new injectors? Also one of my elec connectors for the injector was loose and CEL came one. All I did was push it on hard gave it a dab of super glue and all is good now. I would start with the connections first.

You said your CEL was on. What codes is it throwing?

When all hope is lost, and you have run out of options, you can always break out the "HOLY HAND GRENADE"!!!! It may not fix it, but you will feel a lot better.
