Hey guys, so I picked up a mk3 turbo targa top about a month ago with a built engine (eagle rods, cp pistons ported polished head, id1000 injectors, gt3582r, aem ems). I just replaced the chsa of the turbo and now it idles very lean at 3,000 rpm with 16ish AFR's. Originally I thought it was the wideband o2 sensor so I replaced that just yesterday. And yet the problem persists. I noticed the map sensor input is received at 0.83 volts and only goes up to .85 volts under throttle and doesn't build boost. I am going to pick up a new aem 3.5 bar map sensor tomorrow to test it. But any ideas before I proceed?
