That's not a stupid question. If the fuel/air charge were not igniting you
would feel the stumble no matter what the PCM did to try and correct it.
First off some cylinders would be running rich because unburnt fuel would
head out the exhaust and the o2 sensor would get a whiff. I also believe
the PCM can sense a non-fire condition whether it be a lack of spark or lack
of fuel....or either at the wrong time. The PCM has gotten rather smart
especially 97 & up. When you say tach looking normal are you saying that
the RPMs are what you're expecting?

Subject: DML: Spark Plug ? (not what you think) :-)
On the 97 and up Dak's, (V8's) let's say one or two sparkplugs weren't
firing properly or at all. Would you be able to tell this by engine stumble
or would the computer compensate for this and make the Tach look like it is
running normal?
This is not a stupid question because Ron W said "There are no stupid
questions when it comes to learning about our Dak's. Just everyone's
experience". :-) Thanks Ron.
Weird things are happening and I'm just curious that's all.
Thanks Guys
Jay
