Dead center in the picture. My dad felt it could be unplugged. With it unplugged, my engine idle surges from 900-1100 RPM. With it plugged, it idles from almost stalling to 1000/1200. What's the deal with this plug? I'm thinking I may just go MPFI sooner rather than later. But until then, if anyone can help me with this plug it'd be greatly appreciated! Thanks in advance!
