Losing fire

[natews6]

I just did a head swap and what not and now when I get on it the car just dies.. it doesn't do it 100% of the time but i just suddenly dies. It starts right back up so I know I have good fuel pressure, so that makes me believe that I'm losing fire somewhere. I checked the wires real fast and nothing jumped out at me. Any suggestions on where to look?

Unless you went with stock replacement heads it may be a tuning issue. Anything that affects the engine's volumetric efficiency, especially a set of performance heads or a camshaft, will have a drastic affect on the engine's fueling.
