Any ideas on how I can firmly secure this plug? It's very loose and keeps shaking out when ideling.

 

It sounds like the clip is broken on it. You can pick up a new one at Advanced Auto for $19 the part # is TSU 90. Make sure the engine is cold when you change it and don't forget to purge the system afterwards. Oh, and just snug it up don't try to torque on it or it will break. Hope this helps.

Sorry, no pic.

It's on the drivers side of the engine, right in front of the first plug wire near the front/top. It's a two-prong plug in that I noticed was unattached. When I tried to plug it in, it really wouldn't clip in tight? Does anyone have pics of this? I think I may be missing something for the plug to clip into...similar to the connector for the plug in the top of the air lid.

Any thoughts?

 

Sounds like the coolant temperature sensor plug to me. On the drivers side front of the motor on right by the head. They are really easy to break when doing plug changes <img border="0" title="" alt="[Sad]" src="gr_sad.gif" />

Well, that would explain it. After starting up, my coolant temp gauge will be at normal, then after about three seconds of idleing, it goes down to 0, flush left.

Does it seat in the plug tight? Mine does not snap in at all. When my car idles, I think it shakes the plug loose...this can't be normal?

 

It also would be a good idea to put thread sealer on it.
