Definitly have a short. Look first for it in the areas you've messed with last. Sounds like you've spent lots of time under the hood and may have recently yanked the UIM a few times. One dumb mistake I made when removing the UIM was forgetting to reconnect the harness plug back into that ASV (air supply valve?). ASV is the PITA to get to one on the backside of the UIM, close to the firewall. When unconnected or not ziptied out of the way, that part of the harness is long enough to dangle down & hit the hot DP - instant 12VDC short on the EGI circuit when it hits the DP and melts the connector. In my case, the short was permanent since the melted plastic "welded" it to my DP, so it was pretty easy to find & figure out. If yours is just dangling, it might just be making intermittent contact as you drive around.
