help.....
1. Is your car modified +/- tuned? If so, list your mods (possibility of running a low AFR and subsequent fouling of cats, etc.).
2. Related to the above, are you running aftermarket air filters such as Green filters? Check for the possibility of oil or otherwise messing up your MAP sensor.
3. Do you hear any rattling from the catalytic converter areas? (possibility of bad cats).
4. Have you checked all plugs and wires to and from the coil packs?

I am heading to the local auto parts place in the morning by taxi......and looking for the Bosch replacement parts. I can't imagine two ignition coils could have gone out but thinking a common part. Car ran fine for the 80 mile trip but once it cooled off and restarted, that's when the problem started. I once heard a mechanic say the scanners just tell the symptom ( in my case the P0300, P0301, and P0303) and thinking if the O2 sensor is really the fault? How long do the O2 sensors last.
