I sometimes spend time hanging out in my 06 LC during the day.

Today it was hot. I was parked in the shade with the A/C going for about 30 min.
I'm 6'5 and my knee tapped the Center diff lock button at some point. I realized as soon as I backed up. So I disengaged, pulled forward and restarted the truck.

It immediately was sitting at 2-400 RPM's and I could not make it accelerate.

I pulled into another shady spot and turned it off for about 10 seconds.

Started right up and running fine since.
No CEL or VSC alert.

Back story:
I did run a bottle of cataclean through it Monday because of a CEL code P0430 X 2 days. Had no symptoms up to that point other than CEL/VSC alerts. They cleared.

Did the Cataclean create a permanent fix for the P0430 code or did it come back? I have a bottle ready to go in once I get down to 1/4 of a tank. I am getting the P0420 and this is a last ditch effort to clean the cats before I replace them. I have replaced all upstream and downstream sensors and still getting the codes. All fuel trims are good and there is no engine parameter that is out of spec that would ruin the cats. I have read good things about Cataclean so I thought I would give it a try.
