It works by "tricking" the computer back into the cold start mode. In cold start mode, the computer injects more fuel into the motor just like a carburetor does when the choke is on. Other sensors detect the oxygen rich air and adjust the fuel mixture and timing to compensate for this extra income of oxygen making this system near fool proof on performance. T
Errrrrrrr, not thanks! That alone right there would have me running for the hills!
