Im having a couple weird issues with my 97 sport. This is a 4.0/AW4 rig,anyway these issues occured out of the blue and at the same time while leaving work today. First issue I noticed was its 1200rpm idle,Secondly I notice it falls on its face when giving it any fair amount of gas from a stop but runs decent at speed with light acceleration. I also noticed the temp. gauge on the dash to be inop (all other gauges working fine). No vacum leaks and No CEL. Thoughts?
