I got a P1366 code after changing the timing belt on my buddy's 02 odysey. I've checked all the alignment marks, and everything is lined up. The TDC sensors read the proper resistance.
Any ideas as to what else to check? It bogs at 3000rpm and didn't do this before changing the timing belt & water pump. The code goes away if you drive mellow, but as soon as you accelerate it pops up and bogs.
