The 05's and '06s seem to be more notorious for stepper motor issues. So, for the OP's sake, research stepper motors. You can get them cheap on ebay if you're up to the task of DIY.

Try this....just seconds after a cold start...gauge reads "0"....shut car off and restart....does it still read "0?" Sounds like more of a computer issue....not reading the signal properly.
Try setting up an temporary/alternate light from the factory sender and see if it is putting out a good signal when the gauge reads 0. If that works, you know the sender is doing its job...even if previously replaced. Then, track the signal as to where it goes and take readings at any plug it travels thru. Check the wire in and out of the computer....see if the signal is getting thru there. Just keep checking wires and at some point, you will come across the problem.
As with any sporadic problem, you may have to leave a tester/light hooked into the wires to see the reading when it acts up next.
I would suggest you get into a wiring schematic to track this down.

problem is it's warming up here so not it's not going to happen...
this may have to be shelved until next winter.

i posted the URL to the thread in the how to rebuild teh cluster from another user here but i'm nowhere near that technical or patient to do that.
i'm debating if it's worth just paying the $500.00 for a new cluster but at the end of the day it's just 1 gauge and it's very sporadic and only when cold.
I can spend that money on mods to! looking at a header/x pipe combo and was thinking of drving down to Brenspeed on a road trip to get it done.
if the cluster starts failing all the time or if i have the car long enough I may swap out the cluster if it's the actual stepper motor's failing. I just want to make sure that's the issue before i go swap clusters..

Oil pressure
Ok guys I need some help, my 2005 mustang GT oil pressure won't stay up. I checked the oil and it reads on my dipstick, so I tried starting it and it starts, oil pressure regulates then drops and my car dies!! Please help me, I'm new to cars so please don't comment rudely or inappropriately. Thanks.
