Cut the harnes to radio to put after market in and then ended up putting factory back in but car is running funny no power when i step on gas

I think there is one wire in hat harness that saves memory , chimes , etc. If one of those wires are grounding out or something that may mess with the computer , That's why you need an interface for the after market , the computer runs the radio , The days of red wire black wire are over .

Radio typically not related to engine. Did u reattach exactly as b4? Did u hit a wire or vac line wen taking out radio. Recheck

I did hit a wire and blew the fuse for radio. I drove it fine untill i replaced the fuse now when i start it it has normal power lights everything then about a min running it starts dying
