Getting P0301 and a flashing check engine light. Safe to drive it home? 40 miles.

JACK

A flashing CEL is an active misfire — cylinder 1 on your 4.3L. I wouldn't run it 40 miles like that. Here's why and what to do.

SAFETY5/10

DRIVEABILITY7/10

LONG-TERM8/10

// SUGGESTED STEPS

!Don't drive it while the light is flashing — a hard misfire dumps raw fuel into the cat and can cook it.

1.Swap the cyl 1 plug with cyl 3. Clear the code, short test drive.

2.If it comes back as P0303 — it's the plug. If it stays P0301, check the cyl 1 wire next.

3.Still there? Compression test before throwing parts at it.

I don't have a verified plug gap spec for your exact engine config on file — check the underhood emissions label before you set them.
