Yeah It was plastic and paper towels in there. There still debris in there that I need to remove. Hopefully this is the reason why my temp was slowly climbing while cruising.

Alrite guys so i remove all that junk, but there still some debris on the radiator, I don't want to damage the fins. What's the best way to clean it while in the car? Can't I just use a vacuum? Oh yeah and my temp is still climbing while cruising, but stop when at a light. I tested the thermostat in a pot of boiling water and it open up no problem.

You are just shooting in the dark without a scanner. Get a good ALDL cable (NOT Red Devil River), download Scan9495 and eehack, hook it up and datalog it. This will also determine the cause of the SES light. Or you can keep throwing parts at it until you randomly hit on the issue

And also while driving to work Today I had the scanner hooked up to show live data. I noticed this too while warming up that my temp would drop suddenly. It kept dropping to - 40 then back to 180, even while cruising it would show - 40 what does that mean? When I got to work my temp was at 204 in park but kept dropping to - 40 then back to 204. Is that normal range for a 160 stat?
Eh, that's all over the place as if it's a connection issue or a bum sensor. Way too irradic to be normal operation. Mechanically the engine isn't capable of changing that drastically.

I think that temp sensor on the wp is bad. I just replaced that last month, unless it was a defect or got damaged during shipping. I'm surprised the pcm hasn't thrown a ses light.
I can’t say for sure whether it’ll effect the temp sensor but it’s still clearly a problem that needs to be addressed. So... as I always say, start with fixing what you know is broken.

I am gonna start on this later today and take it to a shop to get that wire fix cause I don't know how to fix that myself (Not good with wires) . I'm also gonna expect the thermostat cause of a lingering thought when the last time I tested it in the pot, I had a 180 Stat in there as well. I notice when the 160 stat starting opening is when the 180 started opening. Right there kinda tells me that that 160 Stat is opening up pretty slow. Don't know why Though.

Are you sure you have the correct temp sensor in the w/p? That is a different part number than the one in the cylinder head. I'm guessing the wires pictured are to the water pump temp sensor? You need to follow those to see if they are damaged. It's also possible the bare wire is grounding out causing your erratic readings. Simply wrap electrical tape around bare areas for a quick fix and see if that helps.
