Help: my 03 coupe is knocking
update:so i took my G in this moringat 7:30am and by 11:00am they called that it was ready and everythign was fine, that they did a full diagnostic test on the engine and what they came up with was spark knock wich is caused by the octain or quality of gas i have never put anything but 91 octain form chevron, so know they told me to try other brands of gas and see if the problem continues and if it dose to take it back to them so well see im allmost down with the tank i have know any suggestions on gas brands i should try?
yeah i have a costco membership im gonna try that which is giant brand and im gonna try shell as well, all try two tanks of gas at each one and see it it keeps knockin lol
