having issues with high idle. shop replaced iac valve. looking at scan data seen the engine coolant temp sensor was reading 30 degrees at operating temperature. replaced that now it goes into closed loop. looking at fuel trims bank 2 is very negative. -30 short term so if it was a vacuum leak id expect to positive numbers. also iac count is at 0. idles at 1300 rpm desired 700. got any ideas?
