I finally put on my MSD 6AL ignition and I had to extend all the wires because I mounted it in the car.... I also put on a new battery and cables.... Ever since... I have been getting higher than usual oil pressure.. it use to be around the top of the A (NORMAL) Now it is around the O I did unplug the wire to the sending unit but I put it back on after I hooked up the ground to my timing cover from my battery... also my water temperature is flucuating more now, I do have underdrive pullies, but it is more touchy and sometimes gets around the O (NORMAL) I am lost, this has just started to happen today after the install of those things. What the hell is going on???
