Hey guys, kinda have a problem with my 2001 v6 mustang 59000 miles. Everytime when go uphill and press the pedal little bit harder...a kind of rattling noise comes up. Goes away when I put the car in neutral or when I'm going below 2000rpm. I know it's hard to diagnose stuff over the net...but maybe u guys can help. The car doesn't shake or loose performance in any way...the noise sounds similar to putting a paper card in the a fan...

Thanx in advance...Rheno

Is it when you start the car and it is cold?

What octane you run?

Mine does it too...always has. Its probably just bogging the engine and/or tranny down under load @ too low of an rpm. I either just back out of the throttle a little and slowly accelerate up the hill or downshift to pick up the rpms.

Sounds like classic spark knock to me....if you're trying 93 oct and it still does it maybe you need new plugs?
