spark knock sound under any acceleration
Hi! Longtime reader, infrequent poster.
I've got a 2001 Touring Ed. that has a spark knock under *any* degree of acceleration at *any* rpm. Dealer has changed plugs and reflashed the controller. I've been running premium octane rather than the regular that the manual recommends for close to three months now, I've used three bottles of Techron injector cleaner. I've driven it hard to try to burn out any carbon. No change.
Does anyone have any insight or a solution that I could try?
She's got 79k miles on her. Well out of warranty.
Thanks.
Steve
