Im bout to hit 200k miles for my 08 civic si. I got a couple problems. A/c doesn't work and my radio only last 2-3 mins then it cuts off. might have to do with when my car alarm kept going off at night so I disconnected the battery so it doesn't. I've taken the car all over California and the Bay Area and is still running strong just changed the spark plugs but any recommendations on what I should change next before it dies out on me? Trying to get another 2 years out the car.
