Changed fuel filter, car ran for awhile, now won’t stay running again. Answers?

Thank you for responding. Nothing has been checked that I’m aware of. My husband has been working on it and neither of us are mechanics, he has done a good job at keeping it going for the most part, just trying to save money and keep it out of the shop. It makes a really loud sound when it starts and it will run a minute then dies. He can’t seem to figure out why it won’t stay running. Could it be a clogged cadilitac converter? I wish I knew more about cars, unfortunately I don’t, so I’m hoping to have enough answers so we can get it running again. Thank you again for responding and he is going to start here!

Hi, I totally respect where you are with things and what you're trying to do. One bit of trouble is that I can't really tell what noise you are hearing from the engine. Some noises are catastrophic internal engine concerns, such as valve train issues, bearing issues, and so forth. Then again, if you have catalytic converter baffles that have come apart, you could get some noise from that. It's unfortunate that we can't hear here! I would say it's unlikely you have a catalytic converter problem, and if I was guessing, i'd say you more than likely have an internal engine concern, such as engine timing being off due to the chain jumping time or something like that. I'm sorry we can't help more -- but wish you luck!
