I been restoring a 79 malibu. Over the course of six months ive installed new fuel pump and lines. Got the car running. Got carb rebuilt and a new tank. Then got trans rebuilt. So I then drove it to the audio shop installed radio and alarm. Proceed to joy ride that day. No prob except the exhaust pipe popped off the converter a few times. Stopped at the movies. 3 hours later proceed to drive home. Car stalled. I looked at the gage it was kinda low. Car was running shitty stalled again. But would not start immediately. Was like I ran out of gas. Finally got it going, stop and go to the gas station. Put gas in. Starts by stalling continues and worsens. If I hit the gas it would stall like I'm running out of gas. Took the old converter off same issue. Checked vacuum lines, seamed fine. Poured gas down the throttle started up and ran til the gas ran out. Checked gas filter it was fine. Help! Plx
