207 intake hissing on throttle tip-in

[rekit]

EDIT 2007
Sounds like a vac leak, but tried fogging with starter fluid with no results. Have cleaned MAF with MAF cleaner. 117K miles, runs good except for trying to stall on takeoff, and lots of no-starts with good spin up. Had ECM checked/repaired. They didn't say what was fixed......I did ask, will ask again. Have had car for years, don't recall hearing this fairly loud sucking sound before. Only does it at throttle tip in.

Just found a article on the crappy intake gasket. Got one on the way. Fingers crossed.

Won't let post link yet, but try this:

Wow, no replies......anyway the new $7 intake gasket should be considered a must for these motors at 100k miles. Made a huge difference. That along with cleaning the throttle body. NOTE, these do not have separate idle control valves since they are drive by wire. Took 30 minutes off and 30 min on.
