2003 V10 ignition coil replacement
Hey everyone, new to the forum and I have some questions. First, I have a 2003 F350 with the V10. It is idling really rough and shudders when when driving at lower RPM. Also seems to have less power. Ran a diagnostic on it and the following codes came up - P0306, P0307, P0316. I know the first two are misfire codes for cylinders 6 and 7. Not sure what the third code means. Did some research and decided that the ignition coils for those cylinders need replacing. So my questions are - 1) Is this a correct assumption 2) If so, do you need to pull the fuel rail to replace these coils. #6 I can get to without doing so, but it appears #7 will require the fuel rail to be removed. 3) If the fuel rail does need to be removed, any suggestions or things I should know about this process. Thanks in advance for any help you might offer.
