hi, today i finally replaced the gaskets from the oil return line of the turbo that were sending oil all over the place, PITA job had to remove the coolant to disconnect the turbo cooling lines to have some space to remove the return line, took some time and patience but its done. went to start the car it did start normally but after a few seconds it just stalled now it stalls immediately. disconnected the battery to do a reset seemed like it was going to start normally but stalled again, now sometimes it just stalls immediately or it stutters and the engine shakes all over and dies.

I already cleaned the throttle body a few months ago, replaced all the vacuum lines for silicone ones, I don't think i have any vacuum leaks.

Didn't disconnect any plugs wile changing the gaskets (apart from a fog light).

what could this be?

thank you for any help.

its a 2001 S60 2.0t Manual

 

So let it sit for 24h, today after work gave it a try and its working.... didn't do a think just left the battery disconnected, fan came on witch is strange since its real cold and stayed on a a couple of minutes after shutting down the car...

I can assume its electrical, gona wait for it to give me some kind of codes to pinpoint the problem (possibly coils)
