2001 Volkswagen Bora 1.6L with engine code P0302

Question

Hi, I keep encountering this problem for some time, I changed the spark plugs, plugs, injectors I checked are ok, from what can be? The valve?

Answer 1

Hi there,

I would take a compression test on this cylinder. It is possible you have a valve issue or a problem with the rings.Also, if it's got a rough idle, it could be an issue with a vacuum leak. Try spraying some carb cleaner along the intake manifold when the engine is idling. If the idle smooths out or the engine speed increases, you have a leak.
