marknzv8 Posted March 21, 2022 Report Share Posted March 21, 2022 Hello i am having issues with trying to get consistant return to idle ,i have installed a large duration cam which lacks torque down low/ idle ,i am getting ok manifold vacuum at idle 12-15inhg considering cam,im running seq injection and 8x ls1 coils on a black storm ecu,i have tried many combinations of throttle valve angle (yes reset tps everytime) i have tried a couple of ford new iac valves and understand that some rely on manifold vacuum to seat them and some dont seat at all,i tried modifying a couple to alter seated position ,and have also played with driven freqeuncy,i have altered gain tables to find a ok spot but,thought you may have a opinion/replacement option /advise, i see on the website a note regarding ford idle valve so may be i need to try something different thank you in advance-mark Quote Link to comment Share on other sites More sharing options...
