Engine is misfiring after a tune up amd the check engine light flashes about 4 times when engine misfires. Took it to two place and they say the computer box to diagnois the problem is not getting power and they dont know why. Converter is good. Alternater is good. New battery.

Can you provide me with what they did on the tune up? Like what did they change or check over.

That does not make sense, I would do a full tune up which should be done anyway, here is a guide to help you, and don't forget to service the throttle body.

Original spark plug .................... AWSF-42EG or AWSF-42E
Replacement spark plug .................... AWSF-42EE

Replace the ignition coil and spark lug wires as well, that should fix it. Check out the images (below). Please let us know what happens.
