Hey guys. Got a 04 tahoe 5.3 flex. I’ve kept it serviced well. Has new intake gaskets knock sensors plugs wires. Had ac delco platinum now have the ac delco iridium. Didn’t matter what plugs still does it. My fuel trims are at 0 while idling. Which is perfect. Also forgot to mention have new cats. Magnaflow. New coolant temp sensor. When it’s idling and I watch live data there is no misfire. Not while driving or anything. Just when idling an I barely feather the gas I will get 1 to 2 counts on random cylinders. Never the same ones. Thing idles beautifully and runs great. So I don’t know what’s up. Also u can not feel is misfire. Seems to not miss a lick. Could it be the app or obd2 dongle. Which I’ve tried different apps an different Bluetooth connectors. The one I’m using now is BAFX. Anyone else had this issue.
