Possibly fuel pump weak, have you checked pressure?
Checked for codes?

I was wondering about that. You can edit posts for autocorrect. There are three dots at the bottom next to report.

fuel pump came today....another question..could a bad 02 sensor cause the same problem? falling on its face? the reason I'm asking is because within seconds of a cold start my engine bay gets hot...even my upper gets hot ...like HOT burn you within minutes of idling

 

[General karthief]

I don't think so, that would trigger a cel I would imagine, but that is only my thoughts, not to be confused with any real mechanical experience

Nice car! Hopefully the fuel pump fixes your issue.
