Check the Coolant system, there is a coolant temp sensor that will cause the engine to do this if it is not actually in contact with the coolant. You will need to vacuum drain the coolant, refill then bleed all the air out of the system. On my legend this happened until realized the radiator cap was bad, it had lost it's seal so the coolant system lost pressure. I didn't realize because the coolant reservoir was full, but there was no pressure to pull the coolant through the system. It could possibly be the idle speed motor needing to be cleaned as well. Once I cleaned mine I haven't had any problems ever since.
