Re: Engine Stutter, RPM drop off
I have the same issue. When I pulled the #6 plug, it was pretty dirty with what looks like rust and debris.. I know the truck sat a long time, but I may have gotten bad gas too. I replaced the plugs and seems to make it better.
Pull the #6 plug and look for water intrusion (wetness around the plug tip that hasnt burned off).. I am worried that this may be an intake/head gasket leak....
