Hi Guys, my car is making a weird noise when I accelerate. Around 2000rpm, I could here a weird pulsating, gurgling noise. Sounds like something is spinning. Only happens when I accelerate. Does not make that sound when the car is not in motion.

I recently had the belts, tensioner, fuel filter, water pump and thermostat changed. Could any of those things cause this kind of sound?

Thanks!

bump, I think it sounds like a diesel engine. Doesnt make this sound if I don't step on the gas. Would a defective tensioner make this noise? or a bad fuel filter causing the fuel pump to make this noise? anyone? :(

These are the worst threads to diagnose... how do you describe a 'noise' with words?

Does it sound slightly like metal-on-metal (again, hard to describe)? Could be the lifters.

i have this sound to.......it is annoying as hell

it sounds like a gurgling that is comming from the driver side under the dash. I know it is not the lifter cause it only does it when it is in drive. If i put the car in neutral and rev it up, there is no sound.

it is only when the car is moving.

Check the heat shield near the cat to see if it's loose.

Went to the dealer today. The shop foremen took it out for a drive. He's not sure what it is yet, but it only happens when the car is under load. I have an appointment next Wed. I'll keep you posted. I have a feeling this is going to cost me $$$ :s

okay the dealer is useless. Left the car for the whole day, they said it was a loose heat shield. They fixed it for free, then when I picked it up after work, noise still there... looks like I have to find someone else to look at it.
