Ok, I have a problem. When I started my 84 na this morning it kinda stumbled when I first started it, it didn't want to idle. After feathering the throttle for a minute or two it idled fine. So I let it warm up for about ten - fifteen minutes and when I go to take off it dies. Every time I hit the throttle even a little bit it dies. I cant even get the car to move. I have never had this problem before. Last night when I drove it, it ran fine. It has all new vaccum lines, I put a new fuel filter on and it didn't help. I tested the fuel pressure at idle and its fine, the fuel pump sounds like its working fine, so I'm stumped. Any kind of help would be greatly appreciated.

So I ran the codes and it came up with 12, which is maf sensor or the wiring for it. So I cleaned the plug again and it didnt help. Luckily I just happened to have a maf sensor from an 85 turbo z31, so I tried it and now it runs fine. The maf sensor from the turbo car should be fine on the na car... right? Also, the ecu came up with a code number 23, but the paper I have doesnt show a code 23, does anyone know what this could be?

wow. i didn't believe that the turbo and N/A MAF would be the same so i looked it up and sure enough, Z31 MAF is for all models. i don't see how that can work. i guess stock boost is pretty low for them though.
