2002 mustang 3.8 engine problems
i have a problem with my 02 mustang with a 3.8
the engine light came on and the car has a rough idle and it is obviously down on power. it seems to be miss firing.. i have changed the spark plugs and the wires and it did not change anything. So i hooked up the scanner and found out that there were 4 codes. miss firing at 1000 revs. also miss fire on 1, 2, and 6 cylinder. codes are PO316, PO301, PO302, and PO306.
the car has recently had the oil changed and it has about 65000 miles on it..
anybody else experience these problems and know what the fix is.
