Idle Miss Gone

So for the last 5k miles or so, the new van has had a slight miss at idle under load, and a slight hiccup on WOT. It was never terrible, just enough to be noticeable.



Well, that miss is now gone, as is the stumble.

The plugs had definitely seen better days. No way in hell were they making it to the 100k mile plug interval.



Of course I upgraded to MSD Blaster coils and NGK Ruthenium HX plugs while I was in there.

I may have gotten ambitious and cleaned the casting flash out of the upper and lower intake manifolds for...........reasons.......

Now she idles smooth as silk, has no more midrange hiccup, and seems to have her fuel economy back.
