I've STFA but can't figure out what's going on. I had my timing belt done a couple of weeks ago and since then there has been a consistent squeling belt or pulley sound. The shop has spent some time looking at it, replaced the acc. belt and tensioner but the sound is still there.
The second issue is that my oil temp sensor isn't working anymore. Not only that, when they went in to fix it, they said the sensor isn't even there (the wire or whatnot coming from the engine, sorry for my lack of knowledge on the subject). The temp gauge was working so I don't understand how the sensor isn't there anymore.
Third issue, and last I promise. Starting about a week ago, when I start my car it idles at around 12-1400 rpm and then drops down to normal.
Is there anyway any of this is related to the timing belt? I'd like to have an idea of what's going on before I go back to the shop. Thanks in advance, and sorry for the length!

how long of an idle until it drops are we talking?

pronounced due to the other problems.

Higher idle when cold is normal.
