Truck is surging - Technical Troubleshooting discussion in Forkliftaction's forums

Toyota 8FGU30:
Truck is surging

I have a 8FGU30. Just replaced the vaporizer
This is a 2016 model and has a display on it
I have to set the TPS to between 4.7 and 5 it says
when I get to around 2.5 it seems to start bogging down
Any idea what is causing this.
I know how to set the vaporizer from lean to rich but that is not heliping
THanks

Check the throttle body maybe dirty, it is very important that it is spotless, also after every adjustment make sure you race the unit at full throttle. for 30 sec to reset ecu
And only turn the adjustment screw very little it is sensitive hope this helps
