I'm getting two codes: P1676 and p0102. I have some other issues also... Non working temp gauge, the gear indicator on the inst. cluster doesn't work (and no backup lights) showing a low oil, and low coolant light on cluster, poor throttle response, and intermittantly working fans. One major concern I have is the car I got the wire harness out of was hit in the left front. (right at computer) Some of the wires had chaffing. I was wondering if this could be the root of all of my problems. I'm going to pull the computer out tomorrow morning and check it out. I'm not really asking for answers, just letting you guys know my progress, and maybe if you have any other places I can check.
Just some info on my swap. 99 complete gtp cradle into my 99 gt. While I had the engine out, I replaced all gaskets on top end, added a 3.4 pulley, plugs, t stat, water pump, headers, supercharger coupler, trans filter, etc.. Once in the car, I added a magnaflow catback, and new struts. I have another thread started with my pics from the swap if you're interested.
Like I said though, I'm gonna check those wires tomorrow and hope I find an obvious issue.
