1999 ES300 - What to tackle first?
Hey everyone, so we have this 1999 ES300 and it's giving me the following codes:
P0420
P0441
P0446
And after filling it with gas it has trouble starting.
Which of these codes or issues should I try to tackle first? Thanks.

Could replace the gas cap if you never have.

^^^ you can actually reset the computer without disconnecting the battery. one fuse under the dash and 2 under the hood. the 2 under the hood are ECU & EFI (if IRC) and the one under the dash is ecu as well. disconnect for about 30min to an hr
