first i'd just like to say that not only did i go through the forum, but i literally read EVERY single post pertaining to codes #1, #2, and #22. now what ive gathered is that 1 and 2 are o2 sensor issues. seems that some people have fixed the issue by replacing their sensors all together. some had IAT issues. and a good deal of the posts i read had no real resolution. so my question is that if anyone has some additonal advice, i would love to hear it. like anyone i'd like to be sure that the actual sensor is what i need before i drop $100 on a new one. also, as far as code #22 goes, im not all that sure how to approach that one. although this is my second honda, this is my first REAL car project and im not familiar with vtec pressure valve issues. is it just some piece i can replace? what all can go wrong that will make that code display? please let me know. thanks.
