1mz-fe coil packs, engine misfire dtc p0300, p0301, p0302, p0303, p0304, p0305, p0306

I think this TSB says allot as it offered coil pack replacment under warranty for certain vehicles. ** Don't get excited folks, your warranty is done gone by now. ** This is simply acceptance that there was an issue and some coil packs may not last as long as others.

If you found this article and you are here for one of the Misfire Codes, this is not inclusive to say "its the Coil Pack!" I posted this as a guide to Not Discount that the coil packs could be causing the issue, OK!

{?} I'm not sure why it lists only the Solara VIN!

That's not good. I remember reading this, but I didn't have my engine's VIN number on hand. Now that I do, my 2000 Solara motor falls within the affected VINs.

I'll keep an eye on mine. My motor only had 72k miles on it. The internals are now about 750 miles after my rebuild, but the ignition components are original.

For the record, I have the Diamond coils, not Aisin coils.

The two part numbers I could find are:

90080-19012 (Diamond) and 90919-02215 (Aisin).

So, it appears the Diamond made coils are affected.

Also, Toyota no longer sells Aisin replacements. They're all Diamond coils now. 90919-02215 has been superceded by 90080-19012. So, hit the junker if you want Aisin coils, but that's risky too. The coils list for around $80-90, so you're looking at about $300 for all three. The Diamond coils have higher internal resistances, so they do produce stronger spark, but they also get hotter.

Both are Japanese companies, but the Diamond coils are made locally.

Chris, theres a little bit something for everyone in that link you dropped us! This one was too big to let slip by so I posted it. I wish it had an index. All kinds of stuff in there!

Most of it did not include 95's tho! But I don;t beleive that clears all 95's of issues. Its just not there in that TSB, prolly in another somewhere else!

Hopefully yours doesn't bite you, but I'd grab em from the bone yard while they're avaialable or pay the piper brand new!
