What did you accomplish today?

lol, don't we always do that ;) I just had an intermittent miss on a cyl, turned out to be the connector between the coil and plug, so a relatively cheap fix. YouTube is your friend.
Worse the code you pull only alerts you to the system not necessarily the specific problem. I remember the duh moment when hub informed me of that nuance LOL
 
Better than the old school way of pulling plug wires one at a time to find the one that is misfiring and smashing the back of your hand against the fender well when you get zapped by 60 KV.
Back in the old, old days, we would charge up a condenser and leave it laying on the parts counter. Somebody (FNG) would pick it up sooner or later and touch both ends. Did teach you not to fuck with stuff.

We used to put a piece of safety wire rolled up like solder on the soldering station. I fell for that one once.
You use a meter and test for continuity, saves the zapping part.
Can't test a spark plug that way.
 
I changed plugs in my envoy Denali on Saturday also cleaned mass airflow sensor, throttle body, fuel injectors..... I fixed the skip for now, but cylinders 4,6,7 look like there's a bigger issue. The plug only had about 10,000 miles on them and I was surprised to see the misfire code . I'm going to replace the pvc valve and valve cover gaskets next....139.00$ pvc valve wtf .. thanks GMC.
