The check engine light doesn't have to be ON to store a fault code.

Check the vehicle for fault codes to see if there are any sensors were involved to the malfunction of the engine.

1.Local auto parts stores such as Autozone ( not in California) or Advance Auto parts will scan and retrieve any diagnostic trouble codes ( dtc ) stored in the powertrain control module for free of charge..

2. Amazon.com has the code reader for less than $24.00 dollars.

3.Re-post the dtc's in here " answer question " for further assistance.

Note: we need the dtc's to identify the sensor, there are a dozen different sensors to operate the car.

Visit this site and see all the different sensors.

Maybe there is a gas leakage and is triggered by the heater, Thus the smell.

a friend has a smell like that when his heater is runnin! I narrowed to a leak in his power steering, not large enough to make a puddle on ground but large enough to burn on engine causing that smell when his heater is on
