My check engine and trac off light have been going on and off for probably a year now, I have a special needs kid so yes maybe I seem irresponsible not having taken care of it but I just haven’t had the time or allowance, checked through an auto parts store and took it for a diagnostic through a local reputable mechanic shop that it’s the catalytic converter, I run through fuel much quicker and it doesn’t accelerate as smooth or quick as before, mechanic told me if I didn’t plan on keeping the car for more than 3 years it probably wouldn’t be something worth investing in as it would cost me nearly $3k to replace. Thing is I purchased this vehicle through carmax when I had a very low credit because I was going to school and working full time and my parents car crapped out on me and I needed something asap that being said I still owe like 10k on it 🥲 yes I know it’s fairly depreciated and not worth that but as I said I have other pressing matters in my life at the moment and again as a sole provider to a special needs kid I can’t even think to purchase something else because I’ll surely be underwater and obviously would like to get it fixed just for reliability. Any suggestions greatly appreciated!
