I have an 04nissan altima...about 25500 miles on it. When I accelerate its making a rattling/grinding noise. Not all the time though. Sometimes going up hills, sometimes on flat roads, sometimes if I have my AC on. When I do drive at 35mph I did notice it was more constant. Also when I was sitting in park with the car running, the car sounds like it's going to shut off...kinda like its not getting enough gas. To top it off my SERVICE ENGINE LIGHT came on. It came on last week, but I got gas & the light went off. The car itself drives fine except for the problem I described.
No smoke from the engine, no overheats, my fluids are all at the proper levels.
Any ideas? I take the car in tomorrow to get it looked at but want to be prepared.

Sounds like it has water in the gas. They will probably give it a tune up...they should change the fuel filter, air filter, plugs, and check the vaccum lines for dry-rot. Good luck.

The rattle probably is a heat sheild on the catyletic converter.
The check engine light is most likely due to a loose gas cap.
The vehicle runs an evaporative system pressure test upon startup, If the gas cap is not on tight, it will turn on the check engine light.

sounds to me like its your cat,but it should be ok,if its only got 20,000 miles on it.if the light comes on ,go to auto zone and have then put a diagnoses machine on it,and it should tell you if its electically or fuel problems.

heat shield on the exhaust is the most likely answer.
