No idea but what engine?

For the engine to run at high speed without applying the accelerator it suggests that excessive fuel, lube oil or some other flammable chemical is entering the combustion chamber.
Have you checked that the crankcase oil level isn’t too high?

Oil level is normal

Was the engine oil dropping, did you need to add oil?
EDIT: not sure if your van engine type has an intercooler, if the engine has been consuming oil it can get trapped in the intercooler and occasionally a slug of it carries over into the induction. You can drain the intercooler by removing the bottom air hose and jacking the van so that the open end is at the lowest point, it takes some time to drain.
