Threw the gauges in to make sure they work, the temp, battery, and rpm definitely work. I can't say anything for the rest of them. I don't have a rear axle on the truck so it's not like I can move it, and I only have maybe a gallon of gas in the tank.
While I was warming it up I noticed exceptionally dark smoke coming from the exhaust. Usually when it's cold it will puff out some white stuff until it warms up a bit. So I hop on in the truck and rev up to 3000RPM, notice some little chunks coming out. So I rev a little more.. and a little more.. now it kind of sounds muffled. Then POW out goes a flaming mouse next. Gonna be fun cleaning that up. I think they were still in it too.
