Butch456 Posted August 21, 2018 Share Posted August 21, 2018 I have a1995 lexus gs300 that warms up fine but after the first 5 minutes it bogs down and idles ruff. All this happen right after I changed the alternator. Quote Link to comment Share on other sites More sharing options...

dcfish Posted August 26, 2018 Share Posted August 26, 2018 Does giving it gas get it back running, I ask because it can take a while for the ECU to read all signals again, Usually around 100 miles or so. Quote Link to comment Share on other sites More sharing options...
