I'll keep it brief and to the point.
B18B1 block
B16A2 head
No major modifications.
Yesterday I threw a CEL, code 1 - o2 sensor which made the car bog down/missfire a bit, nothing major, had a problem with an o2 sensor with similar symptoms last year, went away on its own.

Today, driving, rolling in neutral to make a turn and the idle just went bat **** insane, jumped to maybe 2k and then down to 0-500, the sound it made sounded as if only one cylinder was firing.

Tried to do the paperclip trick to read the CEL and light was just flickering and getting dimmer and brighter like a ****.

Car doesn't start, when the fuel pump was priming there was an incredibly strong smell of fuel.
For about a minute with the car off and all there was a hissing sound coming from the intake as if some pressure was escaping.

A bit before that event the car over heated to about 3/4 of the way through the temperature gauge, don't know just how reliable the reading is.
Thinking the head gasket might have went and the engine is flooding so I will pull the plugs tomorow and try to see something through that little hole.

Your thoughts on the matter will be greatly appreciated.
Thanks in advance.
