My buddy fixed his by adding a cowl hood and the problem went away... I didnt have $550 plus shipping so I cheaped out lol.

I put a 180 stat in and it doesn't seem to be running much lower... I could kick myself for not running the 160 now, but I was afraid it would make it want to dump more fuel to bring temperature up. I'm gonna throw one in to see what it does, as I'm still running around 190-195 moving, and close to 200 idling. radiator has been thoroughly flushed several times and the mechanical fan is good. I also wired in that thermostatic controller, and it seems to kick on around 170. Wired it straight to battery, and it cycles 3-4 times after shutoff. also no problems with battery, as i actually was sittin listening to stereo for 4 hours after it did its cycles and it still cranked well.
I also replaced all injector o-rings when I replaced the #3 injector. There didn't seem to be any leaks before or after this.
