I have a fuel gauge and at idle my car is at 38psi and at full throtle it does 42-43psi's I have a feeling that is alitle lean? Im running Sunoco 94 with a Skunk2 ecu

also I installed an A/F gauge and at Idle I get 4 red lights meaning lean
is that normal at idle?

thanks

 

I'd look for a walbro in tank fuel pump. Can't beat em.

i believe that you are fine !! if your A/F gauge is automemter then please don't worry about the gauge cause autometer A/F one is sucks....you know what i went dyno couple days ago A/F is ok but only autometer A/F gauge is weird!!!! so.....don't worry

 

Its kinda hard to tell sometimes with the autometer A/F gauge all those damn lights flashing at the same time! anyone have the same problem?
