vacuum leak?

I have a cel for p0201,03,05,07(driver side injectors) and the abs light. I discovered i have a brake booster leak that i suspect is throwing the abs code. what I want to know is if that leak could be my possible misfire on the cylinders as well?

I don't think a vacuum leak would set injector faults. Check ECM plugs for corrosion.

I have four grounds correct? One behind passenger head one on the block between the headers and the valve covers one next to the alternator on the block and one behind the driver side head. Now as speaking to litle88 he at first thought might be my battery so I took it to charge and they said it was charging just fine then he advised to check my hoses for any leaks. Although I found a leak on the hose of the brake booster behind the intake manifold I'm on the process for more possible answers. I couldn't see any corrosion to my connectors but I'm no expert so you guys tell me what you think thanks I appreciate the help.

Tightened down the brake booster vacuum line and turned the car on and had an engine power reduced light come along with a service vehicle soon light and a service stability track light I don't have a code reader with me at the moment so don't know what could possibly be the codes. I also tried backing up the car and it just died on me out of no where.

you DEF have an issue. be sure to check the fuses under the hood. sometimes they can back out. also check the ground on the front of the passenger head.
