so i checked the ovp relay, and too quickly i thought that was it, since the rpm went up and the car actually held idle and then the rpm went a little down. But turns out the next day my dad tried to start the car the next day and it wouldnt hold idle and warm up. so that only fixed the abs lol. ill have to take a look at that temp sensor and play around with the other relays. thanks for the posts
