    Hemi 5.7
    My truck has the 5.7 hemi and 123k mi. It has always started on the first try cold or hot. lately it will only start quickly (on the first try) when cold? Many times after it has warmed up, it will take a second attempt. It always will start after the second attempt.
    Has anyone seen this? I just changed plugs, and it made no difference.
    Thanks,
    John

    Mine has a similar issue, except it does it at random. It will do it hot or cold, might do it two days in a row, could go 3 weeks before it will do it. Not real sure where to start.
