They are simply scamming you. You are clearly looking like a 'mark', and they are confusing you and stealing your money.



Have they put anything in writing?


Scammers will typically have very little in writing, but will spin the nonsense around what caused it in their verbal pitch.




Since you dont know much about cars, you are kinda stuck- you decide there must be SOME truth, and then spend your time lost in the weeds... (So how much SHOULD an injector and plug change cost???)


The 'smell' was 'gas fouling the plugs'?!?!?


Finally, this is a CPO a few months ago- all this is under CPO warranty, right?????


Please dont move forward- this needs a second opinion.
