Default Does your truck whistle? I fixed mine finally, here's how

After doing some maintenance on my truck, which dealt with the CAI and the throttle body. I took off the throttle body to clean it and the CAI.

Afterwords I was left with a very high pitch whistle. I was determined to figure this out. I searched around and found many people saying oh that's normal. I even went out of my way to make a thread about it on here.

Nothing helped.

I contacted RamTech (member on the forums) and asked him what the torque specs were for the throttle body.

Well guess what folks, there is absolutely no whistle at all now. I believe all the people who I have talked to and have this issue, they just simply need to torque the 4 bolts down properly rather then just hand tightening them.

The specs to torque to are 105 inch pounds. I torqued mine all to 100 just to be safe.

If you have cleaned or removed your throttle body, torque it down!

I noticed a complete difference in throttle response after I torqued the 4 bolts down to 100 inch pounds. I will now guess that the truck before caused the whistle due to air getting between the throttle body.

Just a tip, go check yours out...

And when I say a change in throttle response, I mean a huge change!
