I have run a K&N dropin since the truck was new, 93,000 miles. If it helps performance in any way, it is very slight. I just enjoy cleaning it as part of my maintenance and it has saved a lot of money for replacement filters.

Whats the procedure to clean the drop in K&N?

I just did this on my 97 with the 4.6. A little differant set up. It took a T-20 Security Bit. Thanks to Harbor Freight Tools I had the correct bit in my tool box. I also sprayed the cleaner on the intake temp sensor (at least I guess thats what it was) a little bulb like thing in the air intake tube.

Thanks for the write up.

K&N sells a Recharge kit at the parts stores. Has a spray cleaner(soap) and spray oil. You spray the filter good with the cleaner then wash it off with a hose. let it dry a bit, then very lightly(lightly is the key!)spray it with the oil. Sort of like you do a first coat with a can of spray paint. Let that dry a bit, then reinstall. Very simple, but, if you over oil, it will foul out the MAF.

I bought the actual MAF cleaner from crc and cleaned it well and i still have this very light rough idle and im at 38,600 so i might do plugs at 40k and we'll see. Thanks bluejay for the write up.

BlueJay,
Good stuff in this tech article. Wanted to know if the orientation of the sensor is critical on reinstall...Should the main opening be into the airstream or on the downstream/eddy side of it?
I removed the MAF from a K&N setup to return the truck to stock for trade-in. It's been four years since I installed the hi-flow filter set-up and I don't remember how it was factory installed. Assuming the clip tang on the sensor and the corresponding red, sliding tab on the wiring harness are oriented on top, I have it right.
I am experiencing idle problems and am trying to work them out. The motor dies after returning to idle, during braking from any speed or when idling for longer than one minute.
I have 92,000 miles and original plugs, clean air filter, and just reprogrammed the ECM to Factory settings, after uninstalling a Hypertech program. After the reprogram, I disconnected the battery to reset the computer and dump any trouble codes that may have been lurking. The engine was demonstrating idle problems before I reprogrammed the ECM. The truck is now completely stock, to include the 195 degree thermostat.
Is cleaning the throttle body with carb cleaner spray recommended? I also plan to dump Sea-Foam or an injector cleaner into my next fiill-up. Any other suggestions? Thanks, Tomcat 2004 5.4L Auto 4x4 XL trim

YOu spray down thru the opening where the wires are. Essentially, you are washing the wire sensors.
