Hyundai Repair Questions? Ask a Mechanic for Answers ASAP
Hello, my name is***** is a common symptom caused by a clogged catalytic converter. You can completely remove front oxygen sensor from exhaust to relieve pressure, if that allows engine to run better you know the converter is clogged. Let me know if you have more questions or if there is anything else I can do to help. Thanks.
I still think problem is likely clogged converter. Check for spark, if spark is good then remove front oxygen sensor to do previously mentioned test. Let me know how it goes or if you have more questions, thanks.
