Battery disconnect After reading some threads on installing new parts it was suggested to disconnect the battery for 20 minutes to clear the pcm. I recently did this and WOW. The car runs much better from shifting to throttle response. The car has 9,000 miles on it now and hasn't run this good since I bought it. When I did buy it from the dealer it had 900 miles on it, my question is did the 900 miles I didn't drive the car "learn" the previous drivers habits? Is it recommended to clear the pcm on occasion to "re-learn"? The only part I have installed is the CAI air box.

yeah, I disconnect my negative battery cable periodically...
it helps to clear out all the "learned" parameters, such as the fuel trims, amount of air flow, driving "style/habits", etc etc... gives it a good pick-me-up... it's especially recommended when installing a CAI, so you can reset the MAF learned parameters and let it relearn the new amount of airflow coming in...
which reminds me, I'm about due for another reset...

no, you should be good to go... that takes instantaneous readings and adjusts things as needed on the fly...

actually, when I went to do mine this weekend... I found an easier way... dunno why I didn't think of this before 
in the under-hood fuse box, I just pulled the ECM/TCM 15-amp fuse for 20 minutes and then put it back in... did the same thing... WOOHOO!!
the diagram showing the location is on page 5-97 of the owner's manual...
there are 3 fuses that reference the ECM, but I only pulled the one fuse labeled ECM/TCM - it's located right under the big STRTR relay...
when you take that fuse box cover off, you'll notice on the right edge of the fuses that there's a little white fuse puller... you'll need that! push the end of that onto the fuse and it will clip on... pull the fuse, leave the fuse in that puller, and after 20 mins, put the fuse back in - squeeze the end of the puller to release the fuse from it.
