Well I finally got another bug worked out of my 84 se, Ive isolated the problem down to the air/fuel idle adjust resistor. With it disconnected the car idles great (when under1000 rpm) When I connect it the idle drops to like 200 rpm and misses like hell, There is a good chance its out of adjust but I tried gettin it straightened out and no luck. Is this sensor really necessary? Or is it worth gettin a replacement?
