Help! does anyone have a diagram for how the spark plug wires are supposed plug into a 93 ford crown vic? my uncle installed and is now worse. need check to make sure everything is plugged up the way it should be.

This should do it:

Yep this is good stuff here look for a cracked plug base on the coil and the towers

I have a 1996 crown it's misfire and my temp sensor don't work I changed it put a new one one on still not reading

Here is the firing order diagram:

I would also have someone check the coil packs. They are very bad for shorting out and causing a misfire. Another place to check it the plug gap it should be 0.054 of a inch.
