code 3 - MAP
code 4 - dizzy
code 48 - o2 sensor

did all these codes just come on at once...?
or has the CEL been on and you just finally decided to check it...?

the d15z1 ngk L1H1 o2 sensor is expensive...
if your map is bunk it could throw off the o2 i guess
i would try a new map first and see if that helps
cheap easy fix from the junkyard
see where that leaves you.

use a wire brush on both sides of your grounds and the bolt threads.
freshen them all up...both end...and all mating surfaces
its never a bad idea and can solve many problems
