Hello everyone. I have a toyota 7fgcu30 serial 69552 on lpg with throttle cable not ecs setup. I am having problems with the throttle randomly cutting out. It will run fine one minute then it will loose throttle response. even with the pedal fully depressed it only idles. Recently it has gotten a new propane regulator, filters and a full tune up. It runs fine just no acceleration from time to time. Any help or pointers would be greatly appreciated.
