Man all I have to say is fuck California.

Also is there a way to test the 7MGE afm to see if the values are good? All I've found is the GTE. My shit failed this morning with high CO and HC, NOx was good .......

Sure, it's in the TSRM. There are links to online versions in the FAQ section, but here: http://www.cygnusx1.net/Supra/Library/TSRM/MK3/

Any diagnostic codes stored in the ECU?

Nope ECU is clean and clear. Last year the previous owner replaced the cat and o2 sensor. I've done plugs, fuel filter, valve cover gasket

Cali spec has two O2 sensors. Is the EGR system intact? Are you sure the cat was replaced? Have you checked both mechanical and ignition timing? Test the plug wires, inspect the cap and rotor and as you mentioned, yes, test the AFM.

And also make sure the cat was replaced with the correct one. Grab the part number off of it and make sure it's a Cali spec cat (not federal). If you have to replace it, be sure you buy the correct one. Cali requires any cat on any car that gets replaced must be with an obd2 cat. I'd probably stay away from buying one online, as I'm sure many people are probably trying to sell their old stock of cats that are no longer Cali compliant

ya i have the paper work for the shop repair, its a certified smog repair station and have the smog from them as well. however im not sure if it was dirty of not. i think im gonna just get a dirty smog and deal with it later.

theres a number of reasons it could have failed i believe
-i replaced the battery and drove it there the following day...im not sure if this system is a learning system or not
-that morning i drove straight there so the car might have been cold, maybe it was cramming more fuel down in the cold weather? i know my other car does that alot(rotary)

i cant tell if its a stock cat.....its new i can see that but they welded it on so yeah. i need to check the timing and cap and rotor. however the car runs great. EGR is intact, only thing is its hard starting but i believe its the cold start time/temp. after the second kick she turns on strong. usually in the cold she rumbles to get to idle for a few seconds.
