[s-cars] running rough

[chris chambers]

Nicholas,

Welcome to da list, because you have the 1.8t coils you can check for a bad coil 
quite easily and quickly.
With the engine running simply lift up each coil, which will unplug it from the 
spark plug. 
When you lift one up that doesn't cause the engine to run significantly worse 
you've located the culprit.

The 1.8t coils are a quick fix, but with my experience are prone to failure.

HTH
Chris

Subject: [s-cars] running rough

so i'm new to this list, new to audi and new to urs4 (came from a mk5
GTI). in march i bough a 92 urs4 that's been rs2ed. coil packs appear
to be from apikol (i'm assuming 1.8t coil packs...?).

car has been running real smooth (perhaps a bit rough and boggy when
cold and consuming more oil than i expected... but smooth). tonight i
took it out and it was acting normal with the usual boggyness after
startup but when i stopped at the first light i could feel a
difference in the idle: it wasn't smooth anymore and was closer to 800
RPM than 900+. under load, at lower rpms the engine feels way out of
balance but around 3krpm the engine seems to smooth out and feels
almost normal... but i don't feel like all the power is there or
anywhere above 3kRPM. my guess is that i'm running on 4 cylinders.

can anyone help me with diagnostics on my coil packs? should i just
start with replacing all the plugs? what are some some good diagnostic
tools to have for this engine? other guess/suggestions?

thanks in advance,
-nick
