Error code 77

Unit comes up with check engine light on after several hours of service. Always code 77. Changed out sensor due to wiring rubbed thru. Was good for 3 days. Code 77. Output voltage stays constant , no pulse up and down. I'm assuming that this is a rich signal. Machine has 4435 hours. Was wondering if lp vaporizer is full and needs to be replaced. Is there. Kit available or full replacement ? Will this take care of the rich syndrome or is it best just to hook up the laptop?

Model is a G33P-5 GM 2400 engine. With Woodward lp system

Fact of the week
Bluetooth is named after the 10th-century Viking king, Harald Bluetooth, who united warring tribes in Denmark and Norway. In 1997, Jim Kardach from Intel gave the name to the technology because of its ability to unite different communication protocols, just as Harald united various tribes.
