I had these same 2 codes, dealer had to talk to Lotus Engineers… they ended up replacing the 2 catalytic converters and the O2 sensorsHey, just wondering if you had any further issue's since they replaced the sensor. I recently bought a yr 23 v6 and have the engine warning light showing with P157 & P174 codes (Mix too lean). AA cleared and light went off but back on again now. Thanks!
