I was wondering if anyone has any recommendations for a CD so that I can invest some of my money in and make the most possible money on it over time. Thanks in advance

Okay edit: I do not want to invest, I’m looking to put away money in savings to have it earn interest. Time that it’s in an account I would like it to be no more than 3 years. Is a CD or HYSA better? I was thinking of splitting the money between the two and putting bulk in a CD and some in an HYSA. Also FYI, I most likely wouldn’t need to touch any of the money in both accounts during the next 3 years but I was going to put some in the HYSA just for an emergency fund.

My check engine light popped on the other day and it’s giving me a P1600 code. I’m pretty sure this is the ECM module so I bought a replacement part already programmed to my VIN but once I got the part in, I wasn’t able to get the keys to reprogram to the new part so I put the old part back in.

Anyone have any advice or knowledge before I take to dealer?
