Problem

93 DX, with z6 head swap.
When the car is first started, runs great until about 10 minutes when the car really warms up.

Then the car idles low, as if it will turn off. I press the gas and there is like a second delay before I feel the car start to rev. If I give it to much gas, it feels like it will die. When I sit at stop lights I usually have to keep it reved up to like 2k.

This started after the Z6 Swap
New Plugs, wires
Dizzy was pulled working from another car.

The ground for Vtec is connect to the same ground as the battery, would that make a difference.
02 Sensor is good.

NO CELs,

Any help is greatly appreciated....... THANKS
