misfire after snow storm.

[nolongerseemssofar]

My Trailblazer has been killing it in these recent snow storms over the last week or two. Seems like I'm the only one that can make it to work. Starting today though, on my way home from work, it was misfiring and the SES light was flashing. Haven't checked the codes yet, but I will be doing that tomorrow. Any thoughts on if the weather could have damaged something?

I would think it's just a coincidence. Coil packs are pretty failure prone.

-rephrasing myself...

They're a common part to fail.

Water leaking on to the number 4 plug from melting snow. Start there.

Get the codes read?

We had a few days of torrential rain a few summers ago. The gasket around the hood dry rotted, allowing water to leak into one of the coil packs, and frying it. You probably had something similar happen is my guess with melting snow...

Don't wait too long or you'll fry the cat. Get the codes read.

Fixed it today! Turns out it was not weather realated at all. Just cyclinder #1 ignition coil. I did check the gasket around the hood and its fine. Thanks for the suggestions!
