when you are missing a cylinder you will feel it! i lost one of my
cylinders when the spark boot fell off the plug after washing my engine.
you can feel that thing, there's no mistaking it. also, you will smell the
unburt fuel exiting the system.
if you just have a bad idle or something, that's a different story, but one
(or worse, two) cylinders? you'll feel that!

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?

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
