yeah its the a map code, it makes the car run rich at idol . try messing with your vacum lines, i was getting the same code and it was my vacum lines. make sure to reset the ecu after you change something or you will just keep getting the code.
hope this helps

Ok kool man thanks. yeh it does idol funny. Anyways u know that canister that on the firewall the red braided hose? I didn't plug that in. I was told that goes on the throttle body but the needle is broke its not there? what do i do?

I was missing that vaccuum piece on the TB as well. I bought a new TB, it didnt change anything. My car still idles high (~1250) and the idle is adjusted as far as possible. the pw0 is throwing no codes, although my zdyne does throw codes (and it idles way worse with the zdyne). I was too tired to even look at the code, so I just took it back out. I paid 40 shipped for my TB, maybe you can pick one up if it will make you happy.

Well 40 bucks is not a bad price but if that braided hose makes a difference i'll get it? If not then i won't. My car is not running rite. I'm gonna replace my map sensor and i hope it goes well after that! Thanks.
