Thanks!
I got my over heating issue fixed today! The car was thinking it was over heating and shutting down but it never actually over heated. It had bad ect or etc? sensors. I also fixed my reverse issue. Ever since I got the car, every time I put the car in reverse it would pop out of gear. I thought it was the transmission, turns out theres a bolt at the shifter and whoever put the short throw in put it in too much so the shifter never went all the way in gear. So crazy how something that annoying (both the over heating and reverse), that I've dealt with for over a year, could be such simple, cheap fixes.
I also might have found a new engine for my car. I wont say anything else but if I get it, it'll have a lot more power than it has now. I'm also buying new exhaust if I get the engine. It's gonna be an awesome summer! haha
