So I got my EFI 5.0 up and running and just pulled the codes. I'm using an rjm harness so I think some are relate to removal of the smog and egr stuff but I just need some help figuring out what needs fixing. I'm having rough start problems. Here's the koeo codes. 81 82 85 84 10 96 Thanks for any help! Also just ran a koer test and it gave me code 6 for cylinders. Is something wrong with my ECM?
