Hi I've had this 93 trooper rs for a few months now and it's been having a few issues since I got it. The odometer and speedometer aren't working. It runs sluggish, sometimes it grabs good and goes but most of the time its sluggish. It runs great I can drive it all day but out of no where it can just shut off on me but always starts right up. Example: I can be Driving then coming to a stop I push clutch in then the idle bounces around from 300 rpm to 1000 rpm then sometimes just shuts off, or it can just bounce around till I make a complete stop then it idles perfect. It never over heats it just has that issue it doesn't happen all the time just sometimes. I haven't been driving it I plan on fixing those issues first. Does anybody now what's wrong ? Should I just do a tune up would that help?

Please help me out!
