SPF4524 started following 2012 Kubota 400/idles good backfires when given gas
SPF4524 posted a topic in Kubota UTV RTV ForumTroubleshooting Kubota 400. it is tough to start, I have to pump the gas pedal. After it starts it will idle, but bogs down and backfires when I give it gas. I've replaced the fuel pump and it did not fix the problem. Any other suggestions that would not require replacing throttle body and ECU ?
