Are those red painted looking threads supposed to be shower? I'm not sure what it exactly is.. But it's right under the fuel rail on the drivers side. And has a plug on top..
Also sounds like air is seeping out somewhere in that area as well..
I can not see it well but it looks like the coolant temperature sensor.
