2007 Toyota FJ Cruiser 🔧
This FJ Cruiser came in with an intermittent misfire—some days it would act up, and other times it would run just fine.
After performing a thorough diagnosis, we found the root cause: cylinder #6 was leaking coolant into the combustion chamber, causing the misfire to come and go. 😬
Unfortunately, the culprit is a failed head gasket.
Intermittent concerns can be some of the most challenging problems to diagnose, which is why proper testing and verification are so important.
✅ Don’t guess. Diagnose.
