the van is leaking either fuel or exhaust into the passenger area it is strongest when the van has run for a while and the defrost is selected It doesn't smell when the recirulation or the A/C button is on. 2 injectors have been replaced.

Could be coming from the evaporative control system thru vacuum lines to the vacuum operated actuators in the AC/Heater components or the firewall is leaking-Have it detected with a gas analyzer
