Cold the car starts fine, just gotta rev it a little for it to stay running, after about a minute it stays running by itself.
After driving more than 20 minutes when i go to start it again, i have to start it and rev it fast or it will die and wont start for another 10 minutes.

It'll crank and try to start and you can hear an explosion like it starts then dies.
If I gas it while trying to start, it makes it start worse and it wont even have a full combustion cycle.

I'm stomped, tried cleaning the coolant temp sensor, same problem though..
