I recently got a new engine installed on my car and I've been driving it around here and there on little errands. At first, it started up just fine without any problems, but recently, the car has been having more and more problems starting up. It'll turn on in one try, but I have to hold the ignition longer and give it some gas. I didn't really car at first, but when this happens, the car will choke at 3,500K and not go on any further no matter what. Could this be maybe because of a whole on the exhaust system? Also, when I popped my hood, I noticed the rubber gasket around the filter had busted, I fixxed this and no improvements. Anyone know what could be the cause of this?
