Hyundai Repair Questions? Ask a Mechanic for Answers ASAP
Hello I will help you with your question,
The purge system has a valve up front that is connected to the intake manifold. If you pinch off this hose does it still stall?
Try this and let me know what happens
You will need to plug or pinch the hose from the purge valve under and to the reart of the throttle body and see if the stalling stops. It sounds like the purge valve and charcoal canister will need to be replaced if the stalling ceases when you have the vacuum line blocked.
