weird problem...anytime you give it the gas while moving the SES light would come on...code said bad knock sensor, so I replaced it. Now if I run 93 octane while crusing the light comes on with same code....but if I run 87 or 89 the light does not come on. I have replaced the O2 sensor as well. Any thoughts as to why it does not like 93?
