I took my car into a shop for an injector replacement. I got it back still running on 5 cylinders (it ran on all 6 just long enough to leave the shop) and with the power steering no longer working. Any idea what they could have messed up while replacing the injectors that would affect the power steering? My speedo was working fine. My power steering doesn't leak, the fluid levels were fine, and the belt is ok. I'm thinking they unhooked something when attempting to do the injector replacement and when I speak to them tomorrow I'd like to be able to tell them what they may have f'd up (besides the job I paid them to do).
