SR20DET just started but won't idle or rev past 2000 rpm. Bad MAF?

[NorCalDrift]

I just got my S13 started with S13 Black top. Awesome!! Have oil pressure and run on all 4 cylinders but no idle and won't rev past 2000 RPM. Before I just start replacing parts (which is OK @ this point), has anyone had this issue? I'm thinking bad MAF. No difference when it is unplugged. All wires are in good shape (shielded too) and all voltage is good @ the MAF harness. Dyin to drive it. Can't wait to kick the KAAZ 2 way! Any help definately appreciated. Thanks

not passing 2k, I too suspect mafs.

agreed. It sounds like its not getting a proper signal from the MAFS somewhere down the line, so its using the so called "safety profile" that it assumes to get you home if your MAFS isn't working. From what I'm told it assumes a basic air curve up to 2 or 3 K so it wont hurt the engine.

the maf sensor is very touchy/sensitive try turning it if it faces to the side ,turn it up,if its facing down try turning it to face more upwards i had to do that to mine ,mine was facing to the side and then i turned it upwards and it did much better try that before u get another maf sensor atleast
