hey guys... this started about a couple weeks ago and what it is i dunno? whenever i start of (regular acceluration) i hear this creeking sound coming from the engine bay or somewhere in the area. i also hear it when i brake and come to a stop. i asked someone and they said it may be the flex bolts on the exhaust, but i dont think they would make a sound like that... any hints and tips would be appreciated

 

does it happen when you turn or go over a speed bump?

 

nope, the sound is only there when accelerating and decelerating.... i tried listening for it when going over bumps and theres no sound, same with pushing down on the car from the outside... its really annoying

 

belts?

 

Exhaust is hitting a heat shield, belts,

 

i also have a problem almost like that. When I idle with my headlights turned off my car idles perfect, But as soon as I turn them on my idle drops to like 400 and it vibrates and feels like its going to die. It never goes away sometimes it scares me because ill be driving then ill put it in neutral and it drops to 0 and then goes to about 400. I have no clue what could cause that.

 

sounds like ure alternator is having a hard time keeping up, check it with a voltmeter or amp meter or w.e u call it. A/C, PS, and anything else that runs on a belt or pump would do that too.

 

could be ur alternator starting to go. not charging properly, or ur battery isnt able to produce the load required.

 

weird maybe its time to upgrade to something with more power. it would help in the long run i guess because ill be putting my system back in it soon

 

do a load test check battery and alternators charging rate and start from there

 

If you need a Yellow Top Optima lemme know
