Ok 2004.5 convertible with no mods except K&N and plenum spacer. It’s now throwing the same 0302 cylinder 2 misfire code it has thrown two times previously. First time replaced all the plugs and problem went away for about 5000 miles. Happened again, this time replaced coil pack on cylinders 1 & 2. CEL and codes went away again for another 5000 miles or so. Today it does same thing! Cylinder 2 again. It’s intermittent today, running on 6 cylinders then you hear it cut out on cylinder 2. I’ll check the brand new coils and plugs - haven’t had a chance yet - but just curious if anyone has an idea why this same thing keeps happening?

One other odd thing/ potential clue is that not only does this car burn through about 1 quart of oil each month ( which is typical yes?) but it’s also using coolant pretty fast. Today I noticed the catch tank was almost empty. Not sure the two things are related..probably not.
Any ideas? Mahalo!

Well it was just the cylinder 2 coil pack again. No water in the oil or anything else weird that I can see. Changed the igniter and it’s ok again.
