I have a misfire in cylinders 1 and 3 and just got new spark plugs and the old ones were terribly overdue but even after the change there is still a misfire in cylinders 1 and 3 any help?
Because of the site we are on,I’m sure it’s a Mustang. Because of the section we are on, I gather it’s a ‘96-04’.
Other than those things, I’m not sure.
What year is the Mustang in question?
V8 or V6?
What are the codes?
What all have you checked/replaced?
