Need Help asap

[XTCshri2222]

I started my CA up b4 i started to install my stuff, the car ran fine 2 days ago.

It starts and stumbles and stalls or gose into normal idle. When it gose into Idle if you hit the gas, at 2,000 rpms the motor stumbles feels like it's fisfiring, won't pass 2,000 rpms and then if let off it'll go back to idle or stall.

I ran out of time, i didn't get to check the plugs, what could cause this?

What MAF are you using and did you make sure to wire it up properly?

sounds like you have either a bad maf or a bad connection for the maf.Are you using stock maf, are you using any electronic equipment like safcII to control your a/r ratio, if so, disconnect it and give the car a try with stock maf, it should work.

right now in the car is the stock MAF, my RB20DET Maf is in shipping, I just installed the SAFCII about 5min ago hopeing to help figger out the problem.

If you have just installed the safc make sure you have your maf wires( white and yellow from the safc) hooked up right, if you have them backwords it wont run over 2000rpm. good luck

Problem solved it was the MAF, cleaned it up and it ran, then hooked up the SAFC and had the problem of 2k again but that time I had crossed wires like beans33 said.
