This is after a head replacement.

It starts up fine when cold. Runs really sweet. Took it on the highway.

But once it heats up, it dies on idle or in gear.

I checked the timing, have it at 10. Checked all vacuum leaks ect. Things are fine.

I adjusted the idle speed, sets at 700. It starts, seems like it loops and tries to correct itself. That's when it dies. Other times it dies on start up when hot.

I disconnected the Amm, idles fine. I used the old amm, still the same, dies.

There was no cold start valve on the intake manifold. I checked all connections, the adjusted TSP sensor. Idle motor works fine.

I am stumped.
