At 40 mph 2001 chevy blazer 2wd makes an airplane propeller revving high sound not effected by rpm along with check engine, parking brake and abs sensors coming on. Auto zone did diagnostic test revealing p0410 code. They said its secondary air intake failure. Sounds like the noise is underneath the middle of the hood. Engine temp and oil pressure seems fine. What could be wrong? Is it dangerous for me to keep driving tonight?
