Stubborn Misfire on a Hyundai ix35? Here’s What We Found!
We recently tracked down a recurring Cylinder 1 misfire on an ix35. While the ignition coil and spark plug were initially suspect, the true culprit was hiding deeper inside the engine: worn valve stem guides.
When clearance gets too loose, engine oil is drawn past the guides into the combustion chamber. As that oil burns, it bakes heavy carbon deposits right onto the spark plug—leading to that annoying misfire code.
The Fix: A top-end refresh including new valve guides, fresh valve stem seals, and a thorough decarbonization to get this engine running smooth and clean again.
