TBI poping under load

[1979jimmy350]

I working on a TBI engine and when I hit the gas it starts poping throught the Throttle body really bad. I have triple checked the timing, it has new plugs, wires and cap and rotor. This is confusing me what could this be?

i had that problem turned out to be the intake gasket

 

[1979jimmy350]

was it a air leak at the gasket or just a old gasket. This is a new gasket in it

 

[dheavychevy38]

nope air and coolant leak
