New here and I tried to search year specific but came up emty.
I was given this old Ranger and the water pump was leaking bad so I replaced that and did all 8 plugs and all the basic tuneup stuff.
Strange issue is, when it warms up and is idling, it missfires out the tailpipe once every 10 seconds. Comes off idle and drives fine. Just at idle it does this. It'll run 85mph down the interstate just fine.
Should I check timing or ICM? I'm kinda thinking it may have jumped a tooth or two on timing but some of my searches say that the ICM is a known issue in these. Appreciate any advice.
TIA
