Hey y'all. I have a problem with my ram. it is a 1997 ram 1500 with a 360. It has been idling rough and as it warms up it starts to lose oil pressure. it also will have a problem where it will idle rough and at a very low rpm and there will be a hissing sound under the hood. oil pressure also drops. then when I rev it it will return to normal idle. Any comments will be appreciated

 

Start by pulling the throttle body, and giving it a thorough cleaning. Pay special attention to the IAC well. It tends to gunk up, and prevent the pcm from properly controlling idle.
