[s-cars] Coils anyone??

[Ian Duff]

How much patience do you have? You could always pull the coilpack,  
remove the wire from a coil to a sparkplug, replace the coilpack, go  
for a drive and see if the bucking is worse. Rinse, repeat, figure  
out which cylinder is hosed. Or you could just unplug injectors one  
by one, drive, rinse, repeat, see if that tells anything.
