PVC and EGR cleaning now firing on only 4 cylinders

Changed out the pcv separator. All ports looked good. Egr was clean and is functioning. For some reason started her back up and it was running rough. Pulled plug wires one by one and there is a cylinder not firing. I'm thinking maybe I damaged one of the injectors or something....Maybe it got dirt on it...not sure. I have a spare car so I will swap out injector on non-firing cylinder first thing in the morning. Any other ideas

Likely an injector problem. Did you pull the fuel rail? If so, pull it again and make sure you didn't loose an injector seal. What codes to you have?

It's not throwing any codes.....Only drove it around a mile. It is getting spark so hope it's a fuel problem. I will pull the fuel rail back off in the morning. All the blue injector seals are present but they also have a small o-ring on them that could've came off.

Try reading the port for codes even if you do not see a light.

I can try that. I didn't realize you could do that with no cel. Good to know

Note to self...make sure I plug wiring back in that I unplug. #2 cylinder injector was still unplugged
