Just finished up my 5.7 crate motor install with the MP harness and ECU. Car starts and runs great, but I noticed a slightly rich exhaust smell like my old 340 when I pull in garage after driving, slight but there. ECU is throwing the following codes, 4 of them are related to the 2 rear O2 sensors. Factory cars come with 4 O2 sensors, this crate install only requires 2. So I'm wondering why they didn't disable, and is the cause of the rich smell? P0138, P0158: O2 sensor high voltage Bank 1 and 2, sensor 2 P0038, P0058: Heater control high, Bank 1 and 2, sensor 2
And P0443: Evaporative Emission Control system, purge control valve I have this nipple capped, isn't this the "gas cap check" code?
Called the tech line and they had no idea, guy kept telling me I need to move the air filter to get cold air.
Anyone have a similar issue?

Looks good, colder air should help. I didn't go the extra mile and put my filter in the usual spot. Car runs amazing, so much nicer than the old 340 I'm not looking for every last HP, it will see way more Hwy miles than 1/4 mile blasts
