LB7: new injectors and some smoke
- Thread starter trevrosborough
- Start date
I just put 20 over stock injectors in and an Airdog 2 lift pump, the truck runs good but when it gets warm it starts lopping when I am coming up to a stop.... Is that hurting anything and how can I get rid of that??
I replaced the FPR already.... the only lopping is when im coming to a stop, when im at idle it doesnt.
Do you have an Airdog on your truck, is so try turning down your lift pump pressure.
