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

My 2000 does this and it's the wiring harness where it goes between the door and the cowl. There's a loose connection in there somewhere. If I move the wires around with the door open (where they go through the body) it works again.
SOURCE: need to replace fuel pump on 97 buick la sabre
it's in the fuel tank! need to get it u in the air about 4 or more feet of the ground. you may get away with it being less and there is two straps holding the tank it they are attached to the body with 15mm bolts. you will need to disconnect the filler neck where you put gas by taking the hose clamps off and then disconnect fuel lines and electrical after you have it half way down straps removed! ask any more question you have
