Not sure how many Highlander owners scan this forum, but thought I'd give it a whirl.... We have a 2004 V6 2WD Highlander. The V6 is quite peppy, but there is a noticeable lag in acceleration at key moments (like merging onto a highway). The delay is almost 1 second.... Almost like the computer is saying "are you sure you really want me to kick in all 6 of these puppies ?" Once the rpm's kicks in, it fires up just fine. But that delay is quite annoying in key situations. Thanks for any feedback.
