Nelson Tune.... Round2

[GenIII_4Ever]

Well I got my tune today. Seems to be just like the other tune was. But that tells me it wasnt the tune the whole time. Allen I know you said its prob the fuel pump. But what about the injectors? Im using a used set I bought off a member from pt.net? Would a bad injector cause it to stumble and lose power when I accelerate?

If you need more injectors to test out. I have a bunch of used ones. your welcome to them.

Nah my dad has a 05 Silverado his company gave him for a work truck. It has the 4.8 in it. I think ima yank the rail+injectors off it and test them on mine. That should tell me if its the injectors. If it doesnt ill be buying a fuel pump. Then if that isnt it ill swap O2 sensors. If that isnt it

have you changed the plugs? Just a wild guess but mine has done the same thing and that was the cause after i spent weeks hunting. Just an idea.

If those injectors were sitting around for any length of time, they are probably sticking, also, like we spoke about, check that fuel pressure just to be sure.

any truck from '00 to 04 will work with your setup, stock 24's.

Yah ima check my fuel pressure today and swap the plugs.

Well had a chance to check my fuel pressure at the rail. Idle it sits around 58-60psi when im driving around its 60-63psi. So im stumped besides the O2 sensors I have no clue lol.

[farmtruc]

it might be a bad injector, or dirty one.

[GenIII_4Ever]

Well I added some injector cleaner to it today.. But that stuff is worthless I think. Whats a good way to clean them one by one?

what exactly is the problem? also what did you do prior to this happening? do you do a few mods? if so what did you do?
