Spark-plug terminals..

[Otto]

So for a little project today, the check engine light was on and the ranger was stumbling a bit at idle and was lacking some power. So I pulled all the spark plugs to check em out. The ignition electrodes were pretty good but I cleaned the bits of carbon off with a little billboard tak. But one thing I noticed on 5/6 of the plugs is the terminals(opposite end of the igniter) were loose as hell. Im wondering why the hell would they make little screw-on terminal tips that can come loose during driving? I tightened them up with some plyers, put them back in and my truck has never run better. And the CEL went off

way back when, spark plug connectors used to be of various types. some had a spade with a hole in that you had to remove the screwed end of the plug, put the connector on the screw the nut thig back on. some had a small hole inside an insolator that had a spring connector which required removing the nut thing on the top of the plug and the connection was made by the spring holding onto the threads. the latest connectors are the ones you are all used to. When you originally installed the plugs did you not tighten the tops, it used to be mentioned in the instructions. Don't ask what instructions are, my hands are tired from typing.
