RE: backfiring issue - 6/9/2007 1:27:55 PM    randy   Posts: 16 Joined: 4/28/2007 Status: offline i was putting in 91 octane because where i live theres only like one gas station that sells 93. So i went there today just to see if it would run any better and it did. But i did use some octane booster aswell. (in reply to Sebba) Post #: 24

That stuttering is called knock.... its basically like taking a jackhammer to your engine. Google search "Pre detonation" "pre ignition" or.. "knock" if you want a technical description. Dont ever put anything lower than 93 in the car _____________________________ (in reply to randy) Post #: 25

One way to find out if bad damage was caused is to look at the spark plugs. Pull one or 2 of them and take a look at the tips... looking for little shiney bits. They will be very small.. so look carefully. That, is vapourised aluminum from the pistons that has cooled onto the plugs. _____________________________ (in reply to randy) Post #: 27
