I took the intake hose off the other day because I was inside the engine fixing power steering issue and noticed this problem. I too have it.
my car looses power on hot days and stalls. Only happens during the summer hot months.
Majorly reduced engine power and reduced gas mileage...Needed to be soaked for almost two days to "ungunk" it.
