So, I just got home, 10:15 PM and I was unable to do the disconnect and key trick. Has anyone else done this to a level where I won't be saying: "Sheesh, what's the worse that can happen...?"

I might be doing this tomorrow evening before going on a long road trip. I would like to see if this will affect my mpg as well as I think it may have dropped a bit, since installing the K&N.

See you all in the AM!

This is probably self induced... ie lead foot from the new sound

No. 'Lead foot' was already there.

Hey...

I've got a 4.7 HO with a K&N intake kit and everythin' is still fine. No power loss or extra fuel consumption. However, you'll notice the extra "grumble" with the absense of the intake baffle (you may also notice a "hiss" like a vent closing when decellerating at 45 MPH ... but I digress).

If it's that noticable have a look at the IAT (intake air temperature) sensor that you relocated with the extension provided in the kit.

1) yes it's stupid but make sure all your connections are good
2) make sure that the cable "splice" is good (ohm it out)
3) clean off your sensor with electronics cleaner

Hopefully this helps.

Great. I had someone else do the work. Now I need to see if they kept the baffle and all.

Then go beat my son up. When he was asked if I wanted to keep what was taken out, his reply was "Why? We don't need no spare parts around..."

I didn't think we had a MAF like Cheby, just an IAT???

Called the shop. They might have not only my old parts, BUT the K&N instructions for installation!

Send son over to pick them up as I don't have time right now!
