- 2007 Mercury Mountaineer
First off, I am a new member here. I have gotten lots of good advice from this forum already and GREATLY appreciate it. Unfortunately, I have a whole new problem.
I have a 2007 Mountaineer with the 4.6L, 72K miles. Today when driving home from work it started shuddering, idling rough and check engine light flashed for a while then went solid. I had the codes read:
P0305, P0307, P0300 and P0316. I got a description of what they were, but I don't know what is causing them, especially the Random misfire. at first I was sure it was a coil pack because I had this problem before, but it was only cylinder 5. Now it's multiple cylinders. I replaced the fuel filter(trying the cheap way out) but that wasn't it. I already replaced all 8 plugs(two of them broke.... that's a whole other story)
Any ideas of what to try without getting raked over the coals at a dealer??? Thank you in advance!!
