ok so I bought this 98 civic dx(d16y7 5 speed)3 months ago. When I got the car I realized there was oil in the antifreeze. Ok yea I figured it was a problem but I never said anything to my parents. Well soon figured out it was a cracked head. But ok to the story. I was fishing with my buddies and we decided to do something dumb. I did a burnout through the yard and ended up hitting the bottom of my car on asphalt. And ever since then my srs light won’t turn off. My car won’t idle under 1300. And when it does it sounds like it wants to die. And my radio won’t stay on. Idk what the problem is I checked all the fuses and wiring. I have brand new alternator,battery,wires from distributor and new plugs. I also have a pretty bad exhaust leak. I’ve dumped a lot of money in this car and I’d kinda like to keep it running through the winter as a beater ig so if anyone could help me it’d be greatly appreciated.
