hello all 1992 ford ranger 2.3 8 spark plug 5 speed. the issue i’m having is on cold start engine will start up and immediately run at like 400 rpm bogs down, runs rich u can smell the fuel . not a problem when warmed up tho it will still not idle up and down on start like normal. replaced iac 2 twice before with similar issues. more new parts ect, tps, also cleaned the throttle body and mass air flow . It would make sense that the iac valve is stuck closed but the part has only been on for maybe 2000 miles
