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.

An additional problem that I have been having is when I come to a stop  

sometimes the van will die as soon as I put in the clutch, or will 
hunt - almost stalling and then back to 800rpm, then stall completely.  

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!
