[s-cars] 1993 S4 miss firing

[Jim Dupree]

With the mechanically injected 911's we could get away
with an NGK plug instead of the Bosch DPO plugs but
they had a shorter life span. 
Actually I found the Bosch F5DPOR plugs for $12.20
each at www.alleurasianautoparts.com If I find
something to bump my order to $75 they'll ship for
free.
Based on the other replies to my miss I suspect I have
a failing coil. I'll probably order the plugs and test
the coils while I am replacing the plugs. If the coils
are the problem I am likely to convert over to the
late 1.8t coil set up, as per Dave Forgie's write up.
I have found a lot of his write up in the archives but
the link I found does not work. Anyone know a link to
all the info in one spot?
Thanks

You can use NGK PFR6Q plugs I have been using them in
the AAN, stock to highly modified for years with no
problems. They sell for just a little under $12.00
