Can fuel from certain gas stations cause a engine light to come on ?
What is your question?
Replaced both kock sensors a one year ago. Now having a problem with engine light coming on (knock sensor low voltage input) when I fill up at certain gas stations. Light stays on until next fill up, then goes out after a few miles on the new tank of gas.

Yes, bought Cheap gas several times . After awhile smelled like sulfer, rotten eggs, light came on. Filled tank with high octane gas twice light went off. Did not use that gas again and had no problems.
