If u extended harness I hope u used maf wire to do this
An check over wires again makes sure there good

Keefs240sx · 02-24-2012, 07:38 AM

It's a wire specialties harness but ppl said I need to check over it but I don't see how that harness can go bad ?

JDMRIDDAZ · 02-24-2012, 07:46 AM

if its WSP harness then its good they r the industry leader for harness i doubt it would be bad
then ur maf is bad
check pins on maf w multimeter w specs from FSM

An jus got the car swapped with red top s13 in my s14 chassis

Keefs240sx · 02-24-2012, 07:52 AM

I've tried to different mafs do you kno maf specs? I can blow at the maf an it changes the idle is that right?

Silvia352 · 02-24-2012, 08:22 AM

check the volatage with a multimeter, it will give you the correct answer without guessing.

JDMRIDDAZ · 02-24-2012, 08:49 AM

sohc maf werks fine
if u have swapped maf w same issue then its wireing or ecu

Keefs240sx · 02-24-2012, 09:10 AM

Tried two different ecu's as well

You check volts at the plug or to test the maf? If maf what should maf read an how do I test it with a meter

JDMRIDDAZ · 02-24-2012, 09:23 AM

not 12v

Keefs240sx · 02-24-2012, 10:13 AM
