All fuel injected cars have crank, cam and knock sensors. And of course there are exceptions to every rule...

 

how about 3.9s... 1995?

I only ask because I think the distributor takes care of that, as when I was trying to fix my idle issues I couldn't find one

 

Thanks to everyone that has contributed to this post. I swapped out the crankshaft sensor and she seems to be running fine. When doing this project it is good to have a friend with small forearms. Little bit of a tight squeeze.

 

Thank you for posting the fix.
