Default Please help!

Hello my name is John and I am new to this.
So I have a 1989 Chevy G20 van. I can get the van to start but it will not stay running. I can keep running if i feathered the gas but if I let off it dies. Also if I push gas pedal to the floor it bogs down. I have replaced fuel filter, fuel pump, spark plugs and wires, distributor and rotor, Map sensor, idle control sensor, ignition sensor module, and other stuff. Oh yeah i rebuilt the TBI. It has a 350 5.0L motor. It seems to be getting to much air sometimes. It will also catch fires sometimes. Can anyone help

I'd suggest look for intake air leakage.-, and of course vacuum leaks.
