Default Need some help with this.

Hey guys, I'm not sure if this is the right section for this, but I'm gonna ask anyways. I did a H/C/I swap on my and then took it to a shop get car tune. Long story short, the car sat on the shop for over a year and they couldn't tune the car. The car has no MAF now as they were going to do a speed density tune on it. Every time you turn the key the car will fire right up and die, it won't idle at all. I did notice that a few cables are cut up, and I was wondering if that could be the reason the car is no idling. I checked the power to the injectors and they are fine, but it's almost like not all the cylinders are firing can some one tell me what is this cable for? Thanks in advance.

Unfortunately there really isn't enough information here. The shop may or may not have changed the tune in the computer. If the shop didn't alter the tune and removed the MAF you will certainly have issues.

I have a MAF that I'm going to put on and see if I can get it to idle at least, what I'm worry about is the cable, because it almost sounds like not all the cylinders are firing
