98 deville, 131k, no hesitation, no stalling. what happens is when I accellerate hard theres a rumble sound. its only during hard acceleration. If I go easy with it, she dont make noise at all. anyone have any ideas?:crybaby:

Maybe a rubber hanger cookie for the exhaust system has broken and something is "grounding" to the body.

hhhhmmmm...i do here something rattleing under the car...slightly noticeable but it rattles a bit..could that be the problem?
This is an easy one, I think. Very likely the infamous front motor mount letting go and allowing the engine to rock too much and cause the exhaust to contact something; exactly what happened to my '97 ETC.

OK..tool her to the shop today to have rumble looked at. It was a bracket thats directly under the exhaust pipe in the middle of the car. The bracket somehow got bent up, so the exhaust pipe was banging on it. I was happy that it was a $10 fix!!:thumbsup:
thanks to all who replied:bouncy:
