    When the car is cold it runs great. Once it reaches operating temp it will spit and sputter and load up. I put a new opti on it a icm module plugs and wires. When I bought the car it was a short block with the rest in the trunk so I had to piece it back together.

    First... welcome to the forum.

    To me it sounds like it's the switch from open to closed loop... can u monitor ur o2 sensors and see if they are functioning properly?

    See if the coolant temp sender in the water pump is plugged in. The sensor in the front of the water pump is for the computer, the one in the cylinder head is for the gauge in the dash.
