Loose spark plug

[02Protege'5]

I started my car this morning and noticed a nocking sound, right away I was worried so I popped the hood and tryed to pin point where the sound was comming from. I found it pretty easly, the far left spark plug wire was bouncing up out of the valve cover! I attemted to push it back onto the spark plug but the actual spark plug had partially backed out and I was loosing compression. I shut the car off and tighned down the plug and the re-seated the plug wire, all is good!

Sounds like it was not tightened enough when installed. Good that the electrode was not smashed flat, that is the VCTS screw hell that the later p5s were recalled for.
