ranger 2.8 holley idle

  1. Ranger 2.8 with Holley 07448, idles at 3000rpm

    Hey I put a 2.8L engine in my '89 ranger. Done the duraspark conversion. carb sucked so i put in a holley 07448. The engine idles at 3-4 thousand rpm. Idle is open just enough to keep it running. Tried frigging with the jets, even with them leaned in 100% the engine will still run up to 4k rpm...
