So in short you have no idea. Lol O2 sensor is not the issue was asking if the header not being hooked would effect it. Does it need that back pressure. I have a Haynes Manuel did everything in it as it said that's why I am asking on a forum were people have experience and might know. But please don't comment if you yourself have no idea and can only make vague under educated statements.
Holy f***, you come in here asking for help and the second we tell you that we have nothing to go off you you tell me I don't know what I'm talking about?
You asked what the unbolted up manifold will do, yeah running with s***ty o2 signals has noting to do with how well the vehicles runs. It's not an issue though obviously, it's not like oxygen sensors do anything important right?
You say you have a timing light and a Haynes manual, the only way you can't figure out where to go from there is if you can't read.
Have you checked the mechanical timing? Pulled codes? Checked compression/spark/fuel pressure? You have said nothing about what you have done to fix this issue, only how you f***ed up this person's car.
Yeah, I'm the one with no idea and making vague statements. By the way its manual, not manuel. Unless you have a Hispanic there telling you what to f*** up next, clearly I'm the uneducated one.
And people wonder why RonJ is the way he is, unreal.
