Here's a good one for ya. My temp gage is doing some really funky shit. With the truck warmed up and just cruising everything is just fine and normal. Now when I go to giving it gas say to pass someone or just wanting to get on the freeway (under load) the temp gage starts dropping just as fast as the speedo goes up. It'll go down past the 1/4 mark and stay there until I let off the gas then it slowly returns back up to the 1/2 just like normal. At first I thought I was seeing things but after a couple of days it's still doing it. So I'm like WTF????? Any ideas??
