Title: strange engine nosie
Post by: xcashewx on May 18, 2009, 04:22:20

the noise sounds like  screeching metal, but the thing is it only occurs when the car is fully warm and the accelorator is pressed to th floor? my guess when driving was the FI pump... any ideas?

Loose fan belt?

If you remove the belts and run the car you should be able to rule out the belts and pulleys off the accessories.  Dont run it long because youll have no water pump, alternator or P/S availiable.  This is done just as a test. Good luck and please keep us posted.

i checked to see if the fan was hitting but its not, when its warm it will only make the noise with full thottle if i ease into the gas to full position it is still there but not nearly as loud??? :/

I assume that you are driving the car when you hear this noise.  If so, check your engine mounts as at full throttle, the engine will tend to twist and possibly something might rub (like the drive shaft if the rear mounts are collapsed).
