93 civic si hb won't start normally in the morning. Have to add gas for it to start. While pressing gas when start up the car will bog few time then starts up directly. After start up, turn engine back to off the car will start up normally. When driving pass 3000 rpm, the car will bog. Below 3000 rpm, runs good no bog. When floor the gas, everything is okay. Maybe no gas pressure when cold. Any help?
