Sorry for the late reply, error codes p0172 and p0175. Also a quick update: got the spark plugs replaced as part of the 60K service but that didn't fix the problem. Left the car for 3 weeks at the shop. They did additional diagnostics, sending data back and forth to the factory. The factory came back that it's "probably" the cats that are throwing the codes. The dealership wants to charge me $6000 to replace the cats + labor, which is unbelievable. Questions: 1. Is it possible bad cats will cause the issue? 2. Anyone aware of the Toyota replacement part for this? It will definitely be cheaper if it's a direct replacement. 3. Wouldn't it be cheaper to get an aftermarket exhaust? Note that we don't have emissions where I live, so I can get away with test pipes, just not sure what parts to buy, so I'd appreciate some help from the experts here if possible. Hi Dave, Yes it's an Evora S supercharged. One thing that I haven't mentioned in the past is that some bearings are getting very loud on hard acceleration. Not sure if it's the supercharger bearings or drive belt bearings. The drive belt has snapped on the previous owner and has been replaced around 20K KM ago.

Hi everyone. I've been battling a check engine light for a few months now and the dealership doesn't seem to get the grasp of it. My car is running rich. Replaced the mass airflow sensor, air filter, a leaking fuel injector, many ECU resets and a vacuum leak but the problem always comes back. My car has around 58K KM still on the factory spark plugs. Fuel economy is terrible in the city, slightly rough idle and a considerable loss of power on lower rpm. It stalled on me quite a few times on hard braking down to a stop. Any feedback is highly appreciated.
