Multiple cylinder misfire with fuel cut off CODES. Along with speed sensor malfunction CODE. And System to lean codes. Where should I start? Speed sensor?

Do you know Susie Q? Just kidding. The misfire and system too lean faults may be due to a vacuum leak, it may need a PCV plate or maybe it got ran out of fuel. The sensor faults should be specific, which speed sensor? I think this needs to be further diagnosed.

Generic fault codes are not helpful, proprietary scanning equipment is needed.
