5.4 V8 2000 Expy.
Just had my caps and plugs done less than a week ago.
Now I'm scratching my head for sure. 5 error codes came up, CEL was flashing at me. Plugged in and this is what I came up with. Cylinders 4, 9, 2, 8 all misfiring. Where did this #9 come from? Also Injection control module performance code PO611 came up.
Any help is appreciated while I research this. Thank you!
