[Biturbos4] Misfire

[Wilson Northrup]

Hey there...

I'm not sure if the $315 was supposed to be a joke? The stock plug 
should be available for under $20 pretty much anywhere.  Last time I 
paid $13 each at the dealer.  A year ago they were $11 each.

Audi Parts Superstore sells them for $16 each.

as mentioned, buy a set at ECS for $70.  (less than $12 ea)

If your dealer gives you some crazy price, be unimpressed and ask them to 
try again.  They can discount considerably on most anything. The 
difference between the ECS plugs above and the dealer plugs is an audi 
logo stamp.  the plug is otherwise the same.


Misfires:
If plugs and coils are expected to be good, consider trying some fuel 
injector cleaner.   I have good luck using the RedLine S1 ( i buy it by 
the case from IO Port Racing) but other products also do a good job.

It is quite common that a bottle of Redline S1 or simliar  can clean the 
injectors sufficiently to address the occasional misfire condition.

The Audi S4 User manual states that a clener should be used on a regular 
basis. If you are not doing this, give it a try and see if the misfire 
condition clears.


Good luck.
