[s-cars] running rough

[Nicholas]

thanks everyone! i did as suggested and pulled the coil packs one by
one while idling. no change when i pulled the one nearest the firewall
(i'm not sure what cylinder that is). i bought a couple cheap coil
packs at my local checker: i wasn't sure what kind of car to tell them
i had but comparing the pictures on the screen it seems apikol is
using the same coil packs you find on a 2003 a4 1.8t. can anyone
confirm...?

i went ahead an ordered 2 (haven't paid for them yet) for $25/coil.
what is a good manf for this coil that might be less prone to failure?
