Loud Engine Noise
 
So I recently changed the IAC as well as the spark plugs in my jeep due to it idling very high (2000 rpms or so). Once I changed all that, i realized that there was a loud sound coming from the engine. It only does it when it idles low, get it up to about 1400 rpms and it stops. It sounds like an exhuast noise, but I dont think so since it stops once the rpms get higher. Any ideas?

It could be a leaking exhaust manifold or even a cracked manifold. What kind of noise do you have?

It sounds like Im running straight pipes, but its under the hood. I thought it was that except for the part that once the engine warms up it almost completly goes away, as well as when I get the rpms up a little.

Could be an exhaust leak which seals off when the part is heated up.
