Hey guys I am a bit confused right now about a check engine light problem that i am having. At lower speeds I have absolutely no problem with anything when it comes to my car. However the second I hit highway speeds I get a code 1 and a code 16. And I really don't get it. I am dumbfounded by this one and can really use some help thanks in advance.

 

Code 1 is primary oxygen sensor and 16 is a fuel injector problem. they are most likey related because a bad injector or faulty injector wiring will affect your o2 readings. I would check out your injectors and the wires going to them and maybe you will find something.. good luck
