code PO300 and a PO307
My 2003 expedition is killing me, in the last week I have had to replace the COP and plug on cylinder 2 and 3, now I have missfire again and its says cylinder 7 and a random multi cylinder missfire, I dont know how to interpet that random code in order to figure out my problem. Is this common for all the coil packs to fail one right after another? My engine has 88K on it and is a 5.4 thanks for any advice on the interpatation of this new code.
