I keep getting a MAF code, when i have it checked i dont remember the code number but it always said High output low voltage. it used to do it all the time until switched out the MAF ( it didnt help any) and re wired the the wires back to the computer. Now it only throws the code when i go past 5,000rpms when it does it it basically cuts the fuel to the truck and i cant give any gas or my afr will go way lean. Also it has trouble idling sometimes once the code is thrown.

I have also swapped computers to see if anything changed but nothing did. i have the passenger side valve cover vent plumbed into the air intake pre blower right after the MAF just like stock was that couldnt be my issue could it?

it was tunned in person by nelson performance and dont think it has anything to do with the tune.

 

anyone have any ideas what it could be?

Thanks

I used to get maf circuit out of range.....you are pullin more air in than the maf is programmed for so it is confused

 

what do i do to fix it? Retune?

Thanks

i think the range of the maf can be fixed in the tune

 

Definitely sounds like a tune issue.

 

Ok thanks guys, i will give allen a call. I might wait tell after the ls1 shootout im sure he's really busy.

Thanks again
