Default Mazda 3 1.6 Diesel 2006 unstable idle and stalling issue

Hello everyone,

This is my first post on mazdaforum.com, nice to meet you all.
I've been having a few issues with my mazda 3, lately it has unstable idle(when hot) and if I turn it the car off while this is happening, it won't start again until it gets cold.

No errors show up on the computer, all the values are ok, I went to 2 garages and this last week to Mazda to do a checkup to see if they could find... Their response, it can be 30 things, so in order for them to find out what it is, they need to replace piece by piece, starting from the injectores, and the value can go to 2000€!!.

Nobody can find out what it is and this problem has been going on for 1year, and every summer is worse than winter and now it's gettign even more frequent! The car had service last month, where all filters were replaced(including fuel filter which is known for this kind of problems).

There are no leaks near the injectores, but there is a small oil leak(nothing that makes you notice excessive oil drop from the engine) but it's easily visible, it's in the air doser, on top of the alternator, and it's a pipe that then connects to the intercooler.

Any ideas? I'm afraid to make a big trip because of getting stalled, like I'm getting lately very frequent.
