I went manual, it works great for me up here in Canada. I can leave it
set on 1200 or 1500 rpm and drive away. As it 'really' warms up, I drop
it down.

Unless you are absolutely certain that there will be no backfiring,
take the extra coupla seconds and put the air cleaner back on. So
far I have only managed to remove all the hair on my arm and face
ignoring this advice... Even if you are certain there will be
no backfiring, I'd still suggest it.
