I havea 2003 Explorer 4x4 4.0L sohc. Been having problems with mis fires and the engine chugging, running rough. I've put new plugs and wires, and replaced an O2 sensor(bank 2 sensor 1). It's been running okay for the past 3 weeks(since I replace the O2 sensor), but it started acting up again. The CEL is on now and it also blinks at me while driving. I had auto zone check the codes and got some new ones.
The codes:
P0171 - Fuel trim bank one condition
P0174 - Fuel trim bank two condition
P0302 - Cylinder 2 misfire
P0306 - Cylinder 6 misfire
P0300 - Random cylinder misfires
P0316 - Crank sensor condition
Autozone told me it could be a Mass Air Flow sensor, but he didn't seem to sure. Any suggestions, ideas?
Thanks
EDIT: forgot to mention that about a week ago, there has been a semi loud knocking noise at cold starts, but it goes away fairly quickly and it doesn't happen all the time. (maybe 3 out of every 5 cold that noise would show up)
