Question about Cars & Trucks
When I start the car, it sound ""like a very strong rattling sound"" in the front under the hood. If I drive it and push the gas pedal down, nothing happen and the speed stay the same like in first gear. Sometimes after 15 or 30 minutes and I turn it off the car, and when I start it again it runs normal.

SOURCE: loosing power at cruising speed
Hi. I have two Dynasty LE cars, (a 91 and a 93). Both have the 3.3 litre. The 1991 had almost the same problem as yours except it would only do it once the engine warmed up, (similar to your freeway issue, given distance and time for the engine to warm up to operating temp.) I had it in about three shops before the dealer found an intermittent fault with the cam and crank sensors. I replaced them and now it runs just fine. I hope this helps.

SOURCE: NO POWER WHEN PUSHING GAS PEDAL
Only way to know whats going on is to retrieve the trouble code for the check engine light by using a OBD II diagnostic's tool, it's likely the poor hesitation in the vehicle's acceleration is causing the check engine light to appear, the OBD II diagnostic tool plugs into a data link connector under the driver's side dash, you can buy one at most auto parts store's, or if you don't want to buy one some auto parts store's will do a autoscan of your vehicle at no cost.

I had a similar problem. The dealer change automatic transmission and differential, but the noise continu. After research on internet i think the problem is the front galiper who create a vibration on the disc wheel and the vibration frequence follow the front axle until interior car. Just press slowly the brake pedal and if the noise stop , that's it the cause i think. I dont change my galiper, but i have a new transmission . :)))

Check the vacuum hoses, but sounds like the IAC or even the o2 sensors. The computer will pick up on the o2 sensors but not the IAC..Go to your local ADVANCE store and they will check on computer for free :)
