Engine Wire Coming Off Coil With Another Port Unplugged.(pics Included) New Bucking Problem. No Codes

I'm having another issue...... this car just won't leave me alone. Had it for 4 years and now it's giving me . When it gets hot (around the M on The normal coolant guage) it'll buck and a very slight misfire not any where as bad as it was but it's un-driveable when it's hot. I can see the tach bouncing around when it's bucking/jerking. Also have a wire crimped tk my coil wire. And there's another one unplugged that I can't seem to figure out where it goes unless it's another diagnostic port.

Found the problem. The pip sensor has broken loose. At least I think it's the pip. It's a little black thing that goes around the distributor shaft
