The coil pack has the *theoretical* advantage of no moving parts.
Also, one coil or drive transistor could fail and let a six cylinder
engine limp home. (not sure about a 4).
The coil packs have been notorious at flash over during humid
conditions, which then burned carbonized tracks into the insulator.
That same sort of thing could happen with a single coil, but with a
single coil there is probably more room to allow a bigger flash over
path. Your description of running badly with humidity made me think
of my experience with coil packs.

Let's see if that new computer fixes your car. Good luck.
If you can start then, I would still look at the engine in the dark
to look for flash-overs on coil, distributor or wires. If the
weather is not foggy, make your own fog with a water mist.
thanks tom
if automobiles makers realise that they can't get away with putting
lighter duty coils in a coil pack then i'd say coil pack design is
superior to distributor.. i'm sure they know well about statistics as
far as reliability is concerned but reducing bill of material still
their number 1 priority..
anyways, i believe my ECU was shot and a new ECU will fix my car..
i went to benltley publisher's site and found this thread.. the guy's experiences with his 98 jetta is similar to mine,
and dave was right, OEM ign coil works when after market units don't..
it's all about the ign module working in conjunction, i guess.. but i
havent replaced mine yet..

and then i found a used bosch ECU with matched part number on ebay for
$47 shipped.. bought it and now i'm wating for it to arrive
if it can run, i'd do a water mist just to see what's going on, but i
can never forget that the only times that my german lady quit on me
was when she's given a steam bath.. lol
will let you guys know how it'll go...
So What happened?
B/c I'm trying to fix my car too
