Hey,
I just picked up a MAF from a 80' 280zx for my 79' 280zx. Before grabbing a used unit I went to autozone to check pricing for a new one. They came back w/ two different parts for my year; one for early 79' ($400) and one for late 79' ($270). I wasn't sure when my Z was made, and the prices were way too high, so I went and grabbed a used one. Long story short after installing the unit from the 80' Z my car runs very rich, 11:1-10:1ish. I was wondering if anyone has used an inline resistor (or even a variable resistor w/ a knob) to lean up the intake charge?
