| Randomly. Well it's pretty consistent but I can't time it. The car sometimes will idle happy as a duck at 13-13.5 then it will lean itself out and go to 15 before it almost seems like the car catches itself and makes it run at 13 again. Somedays are better than others for this, but it still always does this. All vacuum lines, intercooler piping/couplers etc are new, all deletes have been done as well. Also after I boost it sometimes it will stay revved at 15psi then not go down unless I shut off/restart then it's back normal again, this has only happened twice. Car is on stock turbo (rebuild balanced), larger intercooler, rebuild 370cc injector, upgraded radiator, all new vacuum lines everywhere, specialty z tuned ecu. I'm thinking of adjusting the idle down tonight to 750 as it idles at 900 perchance this could be the issue? Not sure about the 1500 under hard boost tho. Other than that car is a top! Thanks!
