Well here I thought it was my new Airaid... Got home from work tonight, and the Airaid CAI was sitting there in a box wating. Disconnected the battery for about 1.5 hours while I did the CAI install, and just took my V6 auto for a quick spin. Wow what a difference. From this thread, it sounds like I got two things going for better performance, 1) The EU reset (temporary), and 2) the CAI (hopefully permanent) Idle is a little rough right now, but now has a nice low growl on fast acceleration below 3500rpm.

From a lot of slow stop and go driving lately around NYC, it was certainly feeling a lot slower than when I really pushed it driving up from NC.

If I had seen the thread earlier, I would have tested just the battery disconnect prior to the CAI install. (no...would not have waited. Figure I will see how it reacts tomorrow during highway commute to work.

I'm just going off of my personal experience. All my FM/SAT radio presets were gone after I disconnected the battery.

I had heard from SCT to do it this way.

1. Turn on lights and Key to on position
2. Pull battery for 30 min to 1hr
3. Turn off lights and key and reconnect battery

This will make sure all capacitors are drained.

My radio presets stayed. Also I have heard that this has helped with the 21474 misfire ECU issues. It did not however help mine. I need to get the FORD IDS ECU factory reset. However I have heard of one car that got this and it still not not fix this ECU bug.

How does the reset effect MPG? I'm getting 32.8 on Hwy with the top up. With the price of gas, I don't really want to mess with the MPG.
