More likely you have oil pressure / oil pump problem, or flex plate cracked (tranny to flywheel interface).
Funny thing I just went outside sto start it and it was quiet as a mouse |

It is a emissions device that injects fresh air into the raw exhaust of a cold engine to aid in the heating up of the catalytic converters to reduce emissions. Cats only work when hot, the faster they heat up the less pollution. |
...and FTR, I don't have SAI. Ever since last January or so, it has been almost quiet as a mouse, less what I believe to be a small exhaust leak causing a faint tick, which I haven't looked into yet.
