If you change the plugs; use the recommended plugs. I used Bosch Double Iridiums in my truck and they've worked good for 4 years now.
About 6 weeks ago I finally changed the spark plugs. So I put somewhere near 180,000 miles on a set of Autolite spark plugs. Two of the spark plugs the center electrode was completely gone. I don't know how the fuck the engine ran and I certainly don't know how it did not throw a code , it still ran very smoothly even at idle.
I’ve found that Motorcraft platinum spark plugs work best in my 1998 Ford Ranger. I tried Bosch plugs and it ran terribly. Nothing but Motorcraft from now on (for Fords).
My 2000 Ford Ranger with a 4-cylinder and manual is just about the simplest vehicle that could exist. SOHC engine, so not much that can go wrong in it. It's very satisfying to work on because you don't experience the shitty feeling of knowing you spent way longer on something than it should have taken.
