4.6 misfireing I have a 1999 Expedition 4.6L (113000 miles)
It has been misfiring for about 2 months now. PO302 code. #2 misfiring... Ok ! I have replaced 2 coils (has 2-4packs) I have put 2 sets of 8mm wires on, 2-sets of spark plugs, and #2 injecter.I have also replaced the fuel filter.Its now getting worst,wont run good but 1 time during the day now.. Ford house says "maybe" valve problem. 1400.00 to rebuild 1 head and labor.... Ouchhhhhhh ! "and hope its fixed"
I find it hard to believe that a valve would act up one day and 30 minutes later it runs great. Have I missed anything ? Thanks in advance ! |
