Electrical

I had to take my car into the shop because the horn stopped working, traced system found shorted horn and blown fuse, also found corrosion on the negative battery cable and the battery was cracking. got that all cleaned up and new battery. Seven weeks later car goes back to the shop, every time i start it it runs for a few seconds, sputters, then dies. electrical issue again, traced system found internal short replaces positive cables and negative cables and bolt special coverage #14311 for the negative cable. one week later back to the shop, same problem but nothing shows on the re-inspection bring the car back home, three weeks
later back to the shop same problem. Traced system found codes P0106, P0171, P1101 all set due to vacuum leak at cam cover diaphragm. replaced the intake manifold,pipe ASM-PCV with charger air bypass, cam cover. What i need to know is if all of these issues could have been caused by the negative cable being defective? Thank you
