Hyundai Repair Questions? Ask a Mechanic for Answers ASAP
Hello and thank you for your question,Is the check engine light coming on and if so can you tell me what fault code and or codes are setting?
If you where not having this problem before the head and timing belt where installed I would go back in and recheck the timing belt alignment.
Unplugging the cam sensor is only tricking the computer and likely masking the problem. If its an electronic concern there should be a code and or codes setting.
Are you getting power to the power side of the suspect injecotr and is so are you also getting the ground switching signal from the ECM?
