So my wife bought a 2006 crossfire 3.2 47000 miles. drove for one whole day and died on her and just would turn over and not start until it cooled down. Drove home and started looking on internet and found this site. Was a lot of help. Decided to buy new RCM and crank and cam sensor. Just to kill all birds one stone. Car would start and then just crank and no start. And then crank long time and try to start like the timing was off or flooding. Found out the crank shaft position sensor I replaced was Bosch and cam sensor was import direct. Changed to Bosch cam sensor and car runs like a champ. But now I have a high pitched whistle noise from behind the glove book when AC is on goes away when fan is on the dot . Button but whistles when in the O fan position. This happens when driving and you lift off the gas and RPMs are dropping back down. Replaced the AC vacuum valve and air filter and still has the whistle. Any help please thanks
