Ok, I can't find my Hayne's manual, or my coolant temp sensor on my 92 3.0 pickup . . The engine has a random miss to it, and I'm trying to isolate it. I've replaced the plugs, wires, cap and rotor . . the only thing that doesn't work is the temp gauge, which someone mentioned might be the culprit. So here I sit with an invisible temp sensor and a truck that still misses.

Any other suggestions if this doesn't fix it?
