i have a 97 cobra and upon start up sometimes i hear a whisstle for like 5 seconds then it stops...wat can it be, also once in a while when i start it up it turns off rite away tha rpms go low and it shuts off...tha only thing ive changed is tha egr valve it helped but hasnt fixed tha whisttle noise and that once in a while shutdown, any ideas thanx

could be a number of things. i would clean it all up, check vacum lines, and gasket for t/b as well.

i did put tha bbk throttle body, for a while i suspected a vacum leak but it would do it all tha time if it was that i think

vacum should do it all the time, but wont sometimes. the t/b will be different and can cause a whistle too.
