Hi guys we just got a 2011 Honda pilot last week for 6500 with 150k miles on it. It's in great shape but the seller said it needed oil change and spark plugs cause it had a small miss to it. It seems to happen when u take off and it gets to the 40mph range it will have a little bucking to it and some times miss around 70mph. I bought band new plugs just like what was in it and didn't change a thing which some of the plugs did look bad. So I thought maybe coil pack was bad cause I have a 08 fit and coil packs went bad on it and made it miss. So I bought set of 6 coil packs off Ebay and swapped the coil packs out and still has the same miss. So I'm out of ideas what the problem could be since both the coil packs and plugs as been change. Any one have any ideas? Theres no CEL on so makes it very hard to find the problem.
