I have been having issues with my car since November 2021. My car would not go over 35 miles per hour, if I let my car sit for a couple of days I would have to jump my car.

I have been having issues with my car since November 2021. My car would not go over 35 miles per hour, if I let my car sit for a couple of days I would have to jump my car. My check engine light came on and then 10 minutes later went off. So I finally got it in to the Hyundai dealership after months of them not having enough mechanics. So they did a multipoint inspection and came back saying the catalytic converter needed to be replaced even though no codes in the system. So I was coming back from Florida when my car stopped accelerating on the highway and my check engine light. So I had to take the long way home which means no highways and anytime I stopped I had to throw my hazards on until it would pick up any speed. I took it to Jiffy Lube in SC and that's when my car was reading 8 different misfire codes so I did my tune up with them and that is when I was told that my engine valve was cracked and dumping oil on my spark plugs and coil pack. Yesterday my engine valve replaced and another set of spark plugs in 2 weeks and it is still reading misfire codes and still no change in acceleration. I have only had my car 4 years and my catalytic converter should not be gone. I have not really moved my car in 10 months because my husband passed and I had 2 surgeries. My family can't take another loss if something happens to me because of this car.
