Temperature Drop

Wild temp swings are typically thermostat issues...

Got mine fixed today. Started thinking when this all started and it was this last winter, what did I do this winter, hmmmm, put a high idle box in the truck, ding ding ding ding. I unhooked it this morning and it went right up to 188 and floated between 188-194 like its supposed to. I guess it never was running low it just read like it was so now maybe I can recoop some of my lost mileage. Thanks Winslow:doh:Just playing bud, I will hook it back up when it gets cold outside again.

It was +7*F this morning. Didn't plug it in last night, because it keeps (since recently) tripping the GFI circuit in the garage.. Was a little tuff to start, but she fired up. about 30 secs later, high idle engaged. 10-15sec after that, 3cyl engaged; that's the first time I've heard it trigger on it's own! I left it idle for about 10-15min in the driveway. Came out to leave, and the temp needle was still buried on 140 (cold). Oh yeah, I failed to turn off the heater blower when I started the truck.

something is not right here, i have started my truck up when it was 4F out and had high idle fire right up and she was hitting 170 withing 8 mins, and then kicks down to idle when she hit 175F
