I use the BG brand induction cleaning kit. Call around to several of your  
local garages and you'll find this commercial system at one of them. We use 
it  at the Honda dealership where I work. It is a 2 part cleaning: one 
additive goes  in with a full tank of gas and the other is introduced through the 
intake as an  aerosol. I like to also use some throttle plate cleaner with 
a wire brush on the  throttle body while I'm in there. Most shops will 
probably do this for around  $100.00. I do it myself with our equipment and my 
cost on the chemicals is about  $45.00. My van always seems to have a bit more 
get up and go after this  cleaning. I am still using my original injectors 
with over 280,000 miles on them  with good results.

I  recently had a "VW Mechanic" tell me that when he listened to my   
engine he didn't hear the familiar "whine" of the injectors doing   
their thing;  He suggested that I have a injector flush to  maximize  
fuel economy.   Do any of the Mechanics on this  Vanagon List have an  
opinion on whether a full injector flush/clean  is recommended or  
would a simple fuel additive suffice for  preventative maintenance for  
the injectors?

Thanks in  advance,
