I HAVE 2000 WINDSTAR 3.8L. PURCHASED WITH 33K MILES, NOW HAS 88K. IT HAS ALWAYS SPARK KNOCKED
SEVERLY UNDER MILD ACCELERATION REGARDLESS OF GAS GRADE OR ADDITIVES( I have tried many).
I HAVE RECENTLY NOTICED THAT SOMETIMES THE CARBON DEPOSITS HAVE ACCUMULATED TO THE POINT
OF CAUSING AN AUDIBLE CARBON KNOCK AT IDLE.
?HAS ANYONE ELSE HAD THIS PROBLEM?
?HAS ANYONE FOUND A CURE OR FIX?
THANKS FOR YOUR TIME.

 

there is a update available for your pcm for this concern .

 

hockeyhitman69,
I greatly appreciate that info, I will be checking on this.
I supose that this is something the dealer will have to do.

 

yes you would get this done by a dealer
