2B72 Variable Intake System, temperature warning threshold

[itscoo2pyopants]

Does anyone have any experience with this code? It does not trigger a check engine light. Im experiencing a rough acceleration on throttle, as soon as i release the throttle the vibration stops. This code popped up this morning, after clearing it the engine is running fine.

Some background, I was experiencing this same rough acceleration about 6 months ago. After pulling the codes it came up as misfire on multiple cylinders. I cleared the code out and the vehicle ran fine for a few months. No codes were popping up, but the rough accleration returned. I replaced the coil packs and spark plugs. Rough acceleration did not improve. Then a couple months later I pulled the code and "2EF4" Thermostat fault came up. I changed the thermostat and cleared the code. The engine was running fine for about a month and the rough acceleration returned, again with no codes present. This morning I get the "2B72". Not much info found when I searched, I cleared the code out for now, vehicle is running fine again.

Any help would be appreciated
