So I have a scanner at my school but there are no current cod just history codes sayin that it was left and right frint tires it never said anything about the back i replaced a front driver side wheel bearing because it was bad I need to do the passanger side soon but should I just leave the abs ...

My traction control and abs lights will randomly come on, also on dry conditions my abs wilcel kick in and tell me I have low traction when I don't and my.brakes will lock as if I was slipping in snow but that
is happening when I am on dry pavement what could be the problem ?

[*]I have an 02 bonneville and Ive had my service engine light, on for a while now which for an emissions leak I have tired everything because my school has a auto shop we've replace both sensors that are involve also a fuel tank pressure sensor, something tells me its the gaskets for my fuel pump ...
