New development today- I installed a cold air intake- the original had a gaping hole in it that I taped up with electrical tape, and the junkyard didn’t turn up a suitable snorkel. I disconnected the battery for a few hours to clear the pcm. Then I started it and ran it awhile. That was yesterday. Today, I pulled the truck out of my working tent after installing drop suspension, and I let it run for a few minutes, maybe 20 minutes. I went inside the truck and noticed the temperature gauge had gone up to the M on normal, I’ve never seen it above “O” the last 15 times I started it. So now it seems it wants to overheat? Still no smoke from exhaust… it’s running in this photo
