LB7: Injector problem

[Dmax1968]

hey im new to the form just have a question to ask you... i just installed new injectors and my truck ran fine at first but not long after it started to lope real bad. was wondering if u guys had any ideas as to why it is doing that?......and has no power when i try to rev it up.

any other problems? lack of power? air in the lines maybe?

Sounds like the fpr sticking for the lope but not sure if that would affect the power that much.Try some power service and a quart of 2 stroke oil with a fill up,after i got my new motor in my fpr was sticking and after the power service and 2 stroke it straightened rite out.

Lubes it up when it lopes if i understand it correctly the valve is sticking and not smooth adjusting the 2 stroke keeps it clean and moving good

a lift pump will also make it lope if the p.s.i. is set too high. the oil/mix will free up the fpr if it is sticking.

Is this a once and a wile thing or every fill up

everytime.. If you dont have any after you have been running it, you will notice a difference.. (or I do.) You should gess less noise as well..

Go to walmart, blue bottle, 2 stroke outboard oil.. make sure it says TC3 on it somewhere..
