Their is a weird clicking noise under the UIM. Its all the time. Idle, through about 4k before my exhaust noise takes over. I thought it would be my Air pump but its not. I thought it would be my alternator but its not. I can also hear it from underneath the car. Its not coming from anywhere past the firewall.

 

I have the same thing some people told me it was normal I could not find where it was comming from.

I am also interested.

 

This didnt start happening till about the beginning of this week.

 

Unless you have larger/aftermarket injectors, it's not normal.

There are many causes for noises like that. I would start first with checking your connections to your coils/plugs. Make sure the plug wires are seated properly and aren't worn. You might use a little dielectrical grease on the seats to help keep it from arcing.

 

I just replaced my spark plug wires, new coil pack harness. What else what it be?

 

Just check to make sure they are seated. It's not uncommon to install new plug wires, not have them all the way seated to slip a little after some driving, then have the spark arc'ing a bit which makes a clicking sound.

 

Alright, ill make sure tomorrow after my powerlifting meet. But I am also getting is checked out by Kyle just in case its something bad.

 

Keep me posted

 

definately

 

i have this exact same problem... i always thought mine was coming from my altinator, or directly behind it somewhere.

 

Mine was the idel controll motor under the uim. Then I fixed that I heard it again and it was the turbo controll sylinoids on the front. You will feel the things hum when you touch them.
