My daughter’s car had a misfire fire so pulled plugs. Changed plugs then there was random misfire. I took it to shop guys put coils on and said it’s same thing still. There is also fuel and air imbalance code. The compression and leak down test was good where do I go from there?

First place I would send you is as far away from the "shop guys" as possible. I just don't understand why they would "put coils on", without ensuring that it would solve the problem? I'm not an expert on this stuff, but let me ask you....Did they charge you for the parts and labor that DID NOT fix your problem?
