TPI boggs down when make sharp turn

Hey guys....yeah my GTA boggs down when i turn really sharp....idk what the problem is. Also, when i turn the car off there is a humming noise coming from the back of the car....fuel pump maybe???. Umm one more thing, at low rpm's it's been missing lately, but like...if i keep the rpm's up, it does fine. IS ALL THIS CONNECTED???? ok well if anyone can help me, i'd appreciate it...thanks

This shouldn't be in the Transmissions and Drivetrain board FYI. Try taking a sharp turn on a full tank of gas. There are fuel starvation problems with the pre 90's gas tanks because they are not baffled. One way to fix this is upgrade to a 91-92 gas tank. The humming noise when you turn your car off is the fuel pump. The fuel pump is triggered by the ECM and the oil pressure sensor on the block so the fuel pump will run until you have no oil pressure.
