TheMrFlippers Posted December 3, 2019 Report Share Posted December 3, 2019 Factory Hitachi, was just gone through and rebuilt. Truck fires instantly, and runs fantastic however at Cold Start it instantly jumps to over 3k RPM, after I tap the gas I can get it down to around 2k. From there it takes quite awhile (more than a couple minutes) to drop, and at the lowest point I can get the idle screw to, it still won’t idle under 14-1500 rpm. Found a couple minor vacuum leaks around the vapor canister, but those shouldn’t affect the idle much if at all. 1 Quote Link to comment
