Checked this forklift out. I had no acceleration and a very rough idle. I took the floor plate with the accelerator and put it on another unit and it worked fine. I saw no issue with the wiring or fuses. Put a throttle body in and it now runs smooth, but still no acceleration. I cleaned and resealed the LPG regulator and changed the filter. I have no idea what's wrong.
Is it possible it has something to do with the SAS, or a harness issue?
Any info would help!!!
