Since the PO has experienced some degree of success by "stepping on the
accelerator", my thought was toward a failed charcoal filter purge valve.
My reasoning being that if that valve has failed open and is allowing fuel
vapours to pool in the intake, say when van parked while shopping, opening
the throttle body valve would indeed lean out the mix and help the the
engine to start.

Not saying the temp II sensor or wiring isn't at fault. But. That charcoal
filter valve is easy to check.

Caveat: I am also neither a mechanic or engineer.   ;)
