My truck 1986 Dodge Power Ram50 2.6L

Things I've done to improve idle & fix slight engine miss:
Replaced PCV valve
Set ignition timing @ 9°BTDC
Cleaned EGR port in intake manifold

Things planned to do:
Remove test inspect EGR valve
Adjust idle air/fuel mixture screw on Mikuni carb
Ajust & set idle RPM to factory specs
Replace Coolant Temperature Sensor (hope it fixes gauge & it's not a wiring problem)

NOTE: Not sure if the CTS is cause for rich running; could be..!

Welcome here & good luck fixing your truck
