I was running the car hard, slowed the car quickly to make a right turn, the car stalls.
I start the engine, and I here this irratic rattling noise from the back of the engine. I drove up the block noise went away. You hear it at low speed under load when the engine is cold, but when the car gets to temp the noise goes away.

Any thoughts???

 

OBTW, the car has no SES lights, Idles fine and drives fine.

 

anyone???

 

Could it be a loose heatsheild?

 

checked that. Nothing is ever that easy for me.

 

I had this horrible noise coming from the back of my motor. It sounded like a bolt was really lose or something, it was like metal clanging against metal. I almost ****ted my pants... Turned out to be a broken bracket on the test pipe. Maybe one of your exhaust welds is busted?
