Closed loop open loop

[Lowranger96]

Okay I'm having issues... I can get my truck to idle in closed loop.. How ever for some reason, when I'm in a partial throttle cruise it doesn't want to stay in closed loop... It was previously running correctly and I haven't touched the tune from what it was. The issue started after I replaced my header gasket and fired up the truck without 2 plugs connected... plugs have been changed but I'm not sure what else may be causing it to go to open loop so easily

I can post a couple logs

Have you tried unconnecting the battery for 5-10 min to clear the learned setting of the ecu?

I tried that once but I'm going to try it again... My o2 sensors have 137k on them so I'm probably going to replace them just so I can rule them out..that and they are probably not the greatest thing esp with a rich tuned boosted motor.. But if it's not those then I'm not really sure what to look at next at least before I put it away.. Just hate to put it up for winter with a hiccup because it's going to nag at me lol
