    My roommate's care has a code for a misfire and looks like time for a tuneup.

    Watched videos and does not look that hard. Involves taking apart the wiper assembly in a similar manner as when I replace the Inverter. I remember looking at the plugs when I did that job.

    I do have a question however. Do I just need to likely replace the spark plugs or will I need to replace her coils at the same time?

    When I have done tuneups on my Fords, I have replaced the wires but not the coil packs although I have replaced the coil packs on them when something seems strange with them. Ford coil packs are not for each plug but in blocks.

    how many miles on her?

    you don't really do a tune up on a priusin the old common sense of the term.

    follow the maintenance schedule. plugs every 120k, and they usually look like brand new.

    to test coils, switch them around to see if the code changes cylinders.

    only by oem parts and from a dealer. either in person or on line.
