| poor performance after upgrades part 2
Well, after double checking every thing was done right and that i didn't forget to tighten up a clamp or something, I borrowed a hypertech programmer off a friend to check for any trouble codes after installing the parts i mentioned in my last post.
now i'm getting po401,po404, po405, p1404, bo229
I followed the instructions for installing the code delete box VERY carefully. Cutting into any wiring harness scares the crap out of me, so i didnt even use crimp connectors, but i soldered all connections and reinsulated them with shrink tubing.
I should also mention that I just got the truck back from GM after losing a head gasket.
wadd y'all think?
