87 Bronco2 2.9 running rough

Postby Bear73 » Mon Mar 04, 2019 7:56 am

I have not replaced anything yet because I just bought it. It runs great while cold, but when reaching normal operating temp it goes to surging like it's misfiring or has bad gas. It only does this while its warmed up. Please help
