I have this strange popping/rattling sound comming from the back of the engine and have no idea what it can be. At first i thought it might be the exhaust pipes loose and hitting around, but i checked them, and it's all good and tight. The sound only happens at idle. Give it some gas and it'll subside, then it will come back. Once the car is moving, the sound stops completely. The car has lost no power what so ever either. The engine also tends to shake when it makes the noise. Any help appreciated.

 

i think i might have that same problem.. but mine is at freeway speeds when i DO let off the gas but i think i have a header leak...


sorry i am not highjacking your thread.... i dont know what it could be

 

bump

 

Oh yeah, just so anyone else has a similiar problem; i figured out what my problem was a while ago. The sound kept getting worse and worse, and would do it while sitting still. If it sat long enough the rattling would be real bad. The problem was that my flywheel was cracked.
