All fluids and filters plugs wires 02s . Coil packs are only a few months old.

It was very nice the past few days, humidity spiked last night with the brief rain at least in my area.

Coil packs do have a high infancy death rate, and humidity will often bring out the worst in them if there is a crack etc, so that is a possibility. :dunno:

Also check wires for burn marks/seperation :smile:

What's wrong with that? I got it with 54k miles



Finally went out and checked. Wire was resting on the o2 sensor. Archin like a mofo lol

anything that runs/drives is really worth a grand, so a 54K example of a buick is a pretty good pickup IMO...

Granted you couldn't pay me a grand to drive it :bowrofl:

Glad you found your issue quickly!

nice. I'm gonna have Tim swap out my front o2 sensor. I have no way to get under the car enough to get it and no real way to get at it from the top.

Take off the upper dog bones, ratchet strap engine forward and watch your hands/wrists for the exhaust gasket between the downpipe and exhaust manifold. Should be enough room. Or atleast someone with smaller hands (no offense -don't know about yours) as mine are on the smaller side. :rofl:
