[Keefs240sx]

Wont rev 1500-2500 an wants to die ? What should I look for ? Pin out on ecu? First sr20 I really need help

[riptor]

need to put more info bro....what were u doing b4 it happened, and why you rewired in the first place.

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

[Keefs240sx]

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]

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]

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?

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

[JDMRIDDAZ]

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

[Keefs240sx]

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]

.5 volts
not 12v

[Keefs240sx]

The maf test that or the plug going to maf?

[Silvia352]

at the connector
