[s-cars] help please, urgent coilpack problem

[Robert Myers]

Dave,

Tracking down that failing coil isn't all that bad.  Disconnect 
injector for cylinder #1 and go for a short high boost drive.  The 
engine, of course, will be missing on #1 and when boost gets up some 
it will also miss on the bad coil cylinder.  It will go from hitting 
on 4 cylinders to hitting on only three.  Reconnect injector #1 and 
do it again on #2.  Repeat in succession until you find the cylinder 
which does not get worse when boost hits.  That is the bad 
one.  Replace that coil and your problem will be solved - for a while 
until another coil goes south.

Bob
