I have had numerous problems with my 01 Corolla. Yikes! You need to understand that Toyota will not submitt to universal parts. You must use their parts. Especially on the Cat Converter. Further, don't EVER go to Meineke for repairs if you haven't already. I use www.partstrain.com to get my authentic parts. They are truly the bomb on pricing.
I had the p171 and p420 codes. I replaced the mass air flow sensor, cat converter, and put on new iridium spark plugs.

it sounds like when the cat was changed they have trapped a wire or just moved one over a bit and its rubbing think about what items this 30amp fuse is protecting are any of the items close to the exhaust or around that area, i dont see the aftermarket starter doing this after 2 years hope this is helpful regards JR

you have to understand that there is a leak in the system other than the gas cap for the evaporative system. The system needs to be professionally closed, and smoke introduced into to find the leak, and a through component check, eg.. purge valve vapor canister vent solenoid all functioning correctly

Make sure that there are no leaks, on your duct hose..where the MAF is located..because if you are getting too much air..the MAF, will try to adjust to it, and it will throw your injectors out of wack, and then you will have a code...stating that you are running too rich, or lean, and then your plugs will foul out, because of too much gas, or not enough...and then it will trickle down to your O2 senors..it's a big chain reaction when it comes down to the MAF sensor...but check your Duct....
