Hi im new here and not sure were to post this. I have a 83 w150 and it runs fine and revs fine in park but when put in gear the engine either dies or idles at 100-200 rpm. Could this be a vacuum or timing problem. I would like some thoughts on where to start.

 

Welcome to the site. You will want to post this in the section that pertains to your vehicle. I can move it but I am not sure of the model (w150?),
