New member here. Since the purchase of my mountaineer I have been exploring the Explorer forums for a couple of months and have found many useful tips on my MACH Audio, door locks, and some other things. Many thanks to all who have made this possible. Now for some fun, Codes Codes. Left side upstream O2 sensor, Cam Sensor. Replaced Cam Sensor, Cleaned Mass Air, and it ran good for a day, now it idles rough and only runs good at full throttle. Any amount of gas and it backfires, coughs, stutters, and has no power. It will however peel the rubber and run a quarter mile like nothing is wrong as long as its to the wood. Any help is appreciated. Thanks. (BTW) tune up is fresh, plugs filters etc.
