I have had the wires changed, spark plugs also the coil pack car has 118,000 on it, I notice the light seems to stay away alot longer in warmer weather. Could it be an Oxygen Sensor, or?
Its a 2001 Ford Taurus

P0304 is a cylinder #4 misfire DTC. That would be the cylinder closest to the passenger side of the car, on the bank of cylinders closest to the radiator (the "easy" bank to access). That code can be caused by low compression in that cylinder (broken valve spring(s), bent/broken pushrod(s), piston damage, cam lobe, or lifter damage etc.), bad spark plug, wire, coil pack, or fuel injector. No, an oxygen sensor would NOT set that DTC. Your vehicle is NOT equipped with the 3.8L V6. 1995 was the last model year that engine was used. But, you know that already.

If plugs, wires and coils are not the issue then the next thing to look at is the injector for Cylinder #4. It may be clogged or it may not be firing properly.

cylinder 4 misfire. If you change the plugs and coil and wires then check the injectors if not you have a bad cylinder.

If your masterpiece has a 3.8V6 engine in it AND the code is for right front and/or left rear cylinder(s) - I bet it's one of both head gasket(s). Kick ford's butt - they've known about this problem for decades, and even extended warranty on certain years 'till 100K.
