07 Charger v-8 missing at idle

Hey i have an 07 Charger and it misses and the code says open circuit on mds selonoid cylinder number 1 and the book says check the wires first and I can see where the previous owner has had to run a new wire for the a/c , and the wires look a little rough, and the engine seems to be missing on both front cylinders and any help would be appreciated.
