100kr?! on scanner


Just installed comp 980 springs, 38# inj, new TT chip and ATR dp At first car would not start, so eric sent me another chip. installed it and car ran but had dead miss on number 4 I found there was no inj pulse from ecm to cyl 4. So replaced ECM under warranty. Now car seems to run fine but look at my scanner readings INT130-133, BLM140, O2 350-720, TPS .48v, IAC70, MAF 9gs, KR100, CLT169 These readings were at idle (800rpm) in park I dont want drive it because I need to visit the local muffler shop to get a test pipe made. Could the knock reading be from the open exhaust?
