The check engine light is on. I replaced a crankshaft sensor

Customer Question

The check engine light is on. I replaced a crankshaft sensor a couple of months ago. After it was installed, the mechanic read the codes. It showed that the O2 sensors needed replacing.
JA: What happens when you step on the gas? Do you notice a rough idle?
Customer: A little. Gas is also leaking from a hose leading to the engine. I have pictures.
JA: What is the model/year of your Hyundai?
Customer: 2005 hyundai sonata
JA: Are you hoping to fix this yourself? What have you tried so far?
Customer: The car would randomly shutoff before I replaced the crankshaft sensor. I was going to install the front two oxygen sensors with the help of a friend. The 2 downstream oxygen sensors I was going to let a mechanic do it.
JA: Anything else you think the mechanic should know?
Customer: I replaced the throttle body.
JA: OK. Got it. I'm sending you to a secure page on JustAnswer so you can place the $5 fully-refundable deposit now. While you're filling out that form, I'll tell the Hyundai Mechanic about your situation and then connect you two.
