This one has me stumped:
I have a 2006 Explorer, V6 4.0, 5 speed auto trans, w/ 130,000 mi. I replaced the oil and filter at about 127,000 mi. Also changed plugs at that time w/ Iridium plugs (that was the first time and none broke off, lucky me), changed front disk pads and checked all fluids. Also added about a pint of "Marvel Mystery Oil" to my oil to clean internal engine components and block.
At around 128,500 miles, I was driving down the road and heard a loud bang/thump come from either under the vehicle or engine compartment. It felt like something hit the bottom of the vehicle, but I didn't see anything in the road. I don't know whether the bang scared me and I took my foot off the gas for a second, or the car lost power for a second. But it kept going and I have noticed no other problems other than my gas mileage has dropped about 3-4 mpg since the bang.
Car idles smoothly, runs smoothly, no noises or vibrations, seems to have same amount of power. Checked for loose wires, plugs, etc. but I can't figure out why the gas mileage has dropped so much after the bang. Since the MPG's were low, I changed the oil and filter again at 130,000. Thought maybe I had a blown head gasket, but oil didn't have water/antifreeze in it, and radiator didn't have any oil in it. Anyone have any ideas concerning "bang" and lower gas mileage?
