Hey Guys,

I have this strange cold start issue that I cannot figure out. When I start the car during a cold start, it idles fine immediately at first but then like 10 seconds will go by and the boost gauge shows vacum change from normal -17 to -10 and I hear this awful sounding rattling noise coming from underneath the car right in front. If you stand behind the car and listen to the exhaust, it sounds like a cold start of a V8 big block (best way i can explain it).

After about 4 minutes or so of the car running like this, the noise seems to rattling noise goes away, the exhaust sounds normal, and the vacuum returns to -17. At first, I thought it was an exhaust leak but we can't figure out. Could a cracked manifold cause this? Anyone else have any idea what else could be causing this? It's driving me crazy!

Thank you!

Does the check engine light turn on or flash?

Sounds like exhaust leak. Check all the gaskets.
