Will do. I know in the past there was a P0140 for an exhaust recirculation issue and one for a random misfire.
In the meantime, are you able to provide a copy of the electrical wiring diagram showing the ecu and throttle body connections?

140 is faulty HO2S no.2 bank 1 most likely chaffed wiring but if light on constant then O2 may need replacing. this will cause gas smell and other issues

What is the best way to check the sensors? I have a diagram showing the location of all 4 sensors (its for a 2002 but i don't imagine there's much difference). Do you have any rough idea of what the sensors cost? Wondering if it would be worth just replacing all 4 and seeing if that makes any difference. Would faulty 02sensor by any chance cause the issue of it not wanting to start? A mechanic also suggested checking the evap canister - haven't done that yet as until we had the diagram, we couldn't find it. It's not where we thought it should be.
