Just installed a smog header on my fj60 all is fine , except it wants to idle at 2000 rpm all the time , checked to make sure the chokes not on. turned the idle ajustment screw all the way out , carb was rebult not that long ago. Found a crack in the intake under the carb before I installed the header. replaced the intake. I believe all the miles of smog hoses are correct but who knows even with the factory manual its hard to get them right. any ideas will be apperciated
