code 23 is mat sensor signal low wich is the manifold temperatur sensor return valtage is low to the computer. check for a sensor that is on the air cleaner housing that has two wires on it. the connector on the sensor is grey in color. if it's not unplugged replace it.
the code 34 is for the map sensor wich is located on top of the engine. but if you have a bad map sensor you would be writing in for a rough running car or something.
was someone unplugging stuf when this thing was running at one time? - good luck

Hi! I have enclosed 3 trouble trees for you. The code being stored is a quad driver error. Quad(which means 4)drivers control up to 4 things. They are located in the engine control module. They provide ground for the items that they control. This could mean a component that the driver controls could be bad or the computer itself. Hope this helps you!
