I have a 1996 ranger 2wd with a 5.0 swapped in. Recently it started running rough at idle. It will idle rough fluctuating between 300-600rpm and die after 30seconds-1min if not given gas. It almost feels as if its got a miss at low rpm's but I think this is due to the rough idle. Also if I am going highway speed and give it more than half throttle going up hills and so forth the a/c will cut off and go to defrost as if it looses all vacuum, my vacuum/boost gauge shows it has no vacuum when I give it full throttle. I have a supercharger but it is off currently because it needs to be rebuilt. I have changed the plugs but to no avail. I have also looked for any vacuum leaks. Could it be the tps or fuel filter?
