Subject: Re: Spark Knock is back.... and I figured out why... And it's BACK AGAIN!!!! by bogus on 2011/10/19 22:09:30 it's back... and I think it's still EGR related... either the valve or the internals are all gummed up with carbon. time to dig deeper... but it's got all the tell tales of EGR... a light stumble at speed, spark knock and a bit fragile feeling overall. It doesn't happen when cold and doesn't happen all the time... gas level is good. Fuel pressure is good. |
