Hi Lapister, thanks a lot for the advice. For the cold start, how cold of the temperature it needs to be to be really considered as a cold start?

Thanks

I did all of these and I have yet to get my SAI to complete. Are you needing to Pass inspection?

If so check your rules as many states (NJ for me) allow 1 monitor to not complete and still pass.

I will go out on a limb and say you may have a leak, failed valve that is preventing SAI monitor from completing. Cold is pretty much first start of the day or many hours between start

There are some that found weak O2 sensors causing the issue.

I still have to deal with my SAI monitor

Per the OBDII manual: "Warm up is characterized by two specific requirements. After the engine is started, the coolant temperature must reach 160-degrees Farenheit and the ECM must see an increase of 40-degree or more in coolant temperature. If the engine is started and is already at 130-degrees that would not constitute a warm-up to the ECM".
