I have been working on my transmission and the car has not been used for almost 3 months. When I reinstalled the transmission and drove the car for the first time (and since then) it has been driving very poorly with the jerking popping and stuttering. The gas was low and so I added some fresh. I changed the fuel filter. I also installed a used LT1 MAF (3.5") with a new Translator. Code 34 MAF keeps showing even after I reset the computer (orange wire off). Does anyone have any ideas where to go next? Thanks.
