So i just replaced all kinds of parts on my hatch. It was working just fine, until one day i went to long john silvers with the parents, and the speed bumps were enormous. I didnt think it would affect my car much, it did scrape. But it just seems like after that speedbump, the car was hard to start. Like if it sits for a couple days, its hard to start, and kinda sounds like it wants to backfire. I think sometimes it does. And it rough idles. I took it to a shop and they couldnt find anything wrong with it. They just said to check the battery, which was bad, so i replaced that. I even tried another ECU, and mine is just fine. So now i just take off the battery cables when i leave it alone! Funny thing is, once it gets started, and runs for a while, i can turn it off and start it up with no problems. Does anyone know what this could be, or how i might be able to correct this problem? It runs perfectly fine, i just want it in top running condition from start to finish. Thanks in advance.
