So I bought a 77 (made in 76) 280z that was dead and stuck the engine/transmission from a 79 280zx 2+2 into it, the thing is, its always had an issue where it would idle really low at a rest,more so when warm, around 500, when i have the idle set to around 1600 when hot just to combat this problem. Anyway i figure out it was most likely the MAF so i ripped it out, cleaned it up, put it back in, and it was working almost perfect for awhile, but now it seems to have died completely. The point of this post is; it never did really work quite right, and my zx engine is slightly different from that of the 76 i put it in, so which MAF do i buy? Will one for a 79zx work better than one for a 76z, or will it even be compatible with the 76's computer?
