My 305 SBC stumbles when hot

chevrolet

#1

I have a 1979 Chevy El Camino I replaced the intake to a edlebrock 2101 intake and freed up the exhaust. Today as I was coming back from a road trip the car started stumbling to almost a dead state when I would get on it. What could be the problem? I am at a loss and this is the only mode of transportation I have.

The first thing I’m going to ask is, does the gas you’re using contain ethanol?

Tester


#3

It’s standard pump gas. 87 octane.


#4

But does it contain ethanol?

Tester


#5

Check fuel pump pressure and inspect the rotor and cap.


#6

I had replaced the rotor and cap when I did the intake swap about two weeks ago. Could the coil being going as well? it’s only a 20 dollar part that I could throw at it, I don’t have a way to test the fuel pump.
