Sorry, I'm sure that this has been covered MANY times and I found LOTS of posts about the AFM in the archives, but I didn't find out exactly where it is. I searched the bentley, but couldn't find it in the Fuel Injection part of the book. Where is it and what should I seal it up with after it take it apart? What I plan on doing is rotating the board in it so that the sensor will move on a new track and also cleaning it with alcohol. Is that right? I also am getting a new cap, rotor, spark plug wires and OXS to eliminate any other possibilities. What else should I change or look at? I think that cleaning grounds (where are they all) and making sure that everything is connected will would be good as well. My original post is below. > Hi all.

I looked in the archives, but there are so many hunting/stalling fixes that I wouldn't know what to start with first. If you want I would be glad to look at things in the archives so that you don't need to revisit topics. I just need a direction to go in. Thanks for the help! Aaron
