I don't know anything about the 2.5, but my 4.2 ignition module went out. Quadra tech used to sell them. I don't know if they still do, I haven't looked at a cataloge in awhile. I had to take mine to the shop cause I didn't know what it was at the time. They got one from somewhere, I'm guessing the dealer.
I'm not sure if that's your problem, just commenting on where to get an ignition module.
