I saw filter.

But what size engine?

Carb or TBI?

Also check your lines for leaks.

If u are loosing injector pulse it's probably the PCM (Powertrain Control Module), check for injector pulse at the PCM using a test light or Digital Mutimeter. I'd suggest using the meter to make sure u have the correct amount of voltage, but a test light will work too.
