Weird Sound At Engine Start
Sometimes when I start my car, a weird noise that sounds like something grinding against something else for 2 seconds. It comes from around the inside center console area. I noticed it usually happens on a warm day and usually when I first start my car for the day.
I think it may be from a door or valve from the A/C system opening or closing. Anyone with any ideas on what this may be?

Are you sure it's not the ABS diagnostic check that's done at start up?

I think this thread is pretty similar and may provide more insight:

So it seems that its pretty common for the TL to misfire upon starting up (especially if it's starting up for the first time in the morning) and this can be due to bad engine mounts or a starter?
It's been abotu 2 weeks since I bought a used 04 TL and because of the misfires I've so far replaced all my plugs and one ignition coil due to my check engine light coming on when starting up nearly every other day.
Does everyone's check engine light turn on sometimes due to this ULEV related intentional misfire?
