I just installed a new dual exhaust (FM40 series) along with Hooker headers and an Edelbrock performer intake manifold. I had a difficult time starting the rig back up as I blew my ECMB fuse. Before I determined that I pulled the distributor thinking it was off 180 so I flipped it and re-wired. After finding the fuse the truck fired but it was obvious the timing was way off! I then pulled the distributor again and flipped it back to the correct position and re-wired and then set the timing. Now the truck idles pretty rough and the Check Engine Light stays on. I am getting codes 33 and 44. I am pretty sure the O2 sensor is shot as this got clipped during the header install but what could that cause both codes? My vacuum lines are connected good except just behind the throttle bodies there is a valve mounted to the manifold kind of short and it has a hose that runs up to a T fitting on the firewall??? That is the only hose I could find and I haven't been able to find pics of an engine bay that would show this. My next concern is on the Throttle Body there is a metal bracket/line that connects to a vacuum type valve mounted on the firewall, this is for cruise control correct? My eyelet broke off the diaphram of the valve so I cannot connect the bracket but my cruise has never worked so I was thinking I didn't need it. Sorry for such a long post I am just lost right now!!
