I have been working on my sister's 2000 ES300 for her. At 99,000 one coil went out. Another at 101,500 and another at 105,000. By the third one I replaced it and the remaining three that hadn't been replaced yet. I got the coils for $60 a piece (They are the Toyota/Denso ones distributed by Borg Warner). For that price it really isn't too drastic on an 9 year old car with original coils. Once replaced it would be smooth until the next one went out. After they were all replaced all has been good. Your problem sounds different. And if the coils were replaced at 100k it would be a complete waste of money to do them all again right now. With all of those misfire codes I would lean towards something like what patchy said. In addition, with just one coil out the car shook bad and was sucking gas down. I don't see how it would even run with multiple coils out without shaking you right out of it.

I'm having an issue now with a family member's ES300 with 93k as well. In addition, I have a check engine light on. I took the car to Advanced Auto Parts and had them read the codes for me without a problem and for free. My understanding was that all Autozone locations do this for free (hoping you will buy parts from them then or at some point). I would just take it to them and request that they run the codes and start from there.
