Question about 1990 Jeep Wrangler
I replaced the tsp and nothing changed.
It may be a bad idle control valve. spray some brake cleaner or other fuel cleaning spray directly into the idle Control valve.it is located right inside where the air cleaner duct work is removed towards the fuel system This gets dirty and builds up gunk . making you car run bad. I hope this helps you. If it does, place a vote.
