[s-cars] 5 new coils

Jamu Coildonator:

Rocket Scientist / aka Crimpmaster Flash (fresh off his "launch cookies"
rush) and I performed resistance tests to all 5 coils, then conductance
tests (per an archived SJM procedure).  Resistance was inconclusive, and
conductance evidenced 4 of the 5 'over limit' (good) and #5 at very
trace amount (compared to SJM baseline).  Pulling an injector and
driving looking for the miss going from 4 cylinders to 3 was
inconclusive as it rendered it too hard to build more than 5psi to
produce the miss.  All five are blue hue'd on the black plastic side.

Prior to this we'd swapped first his POSs into my car (no change) then
his coil cover.  Voila, coils solved it.

Funny tho each time I've fiddled with things in there (even pulling then
plugging in injectors) has provided at least a temporary improvement to
things, must disrupt something enough to help briefly.  

The swap helped psi build w/o sputter initially to 20, then to 18, now
to 12-15.  Again, guess is coils 1-4 following suit of 5.  

Yay!

Thanks again.  Hope our testing assists others sometime.

-Paul

Coilmuncher, which coil did you swap with? the one I sent you was my #2
coil, just wondering if you swapped with the right one... but then again
if you went from 5psi to 12-15psi it obviously improved. Curious that
you can't identify the bad coil... before you outlay the cash, is it
possible to check the POS device? I'm wondering if that has a
contributing factor... I would assume the POS either works or doesn't
but perhaps one of the channels is flaky? 

What coil testing procedures have you and the rocket scientist/mechanic
done so far?

Not sure the price now, but a while back www.germanautoparts.com had
them for $105 each.

P.S. Dealer part number is: 034 905 101 (ignition coil, including spark
plug connector)

So looks like I'll be in the Baloney club of "5 new coils" afterall...
I sorta figured that to be the case but hoped for the short-term
elcheapo fix.  

Swapped in a Jamu-of-Canada donated used one the other night with
Rossato.  As the the pull-the-injector-and-run-WOT method of trying to
isolate the offending coil was inconclusive we instead relied upon
uberkeen Sesame Street Diagnosis (SSD) of (sing along now) "which one of
these things doesn't look like the other" as we compared the resistance
readings of the 5 and then their conductance readings to try to
determine the failing unit.  

Unfort. this only 'improved' my miss situation not solve.  Hey I can now
build more than 5 psi before sputter, but only 12-15.  Makes me think @
150k the other 4 are on well on their way out.  Each have a bluish car
to the outer black case, my guess is they're all toasty.

Baloney...  what was yer source for the 5.  IIRC you found them hovering
just-sub $100 clams somewhere?  Part of me is bummed by the $500
impending outlay... the other is giddy (as you were) @ prospect of lotsa
boost again.  Like it needs to be faster.  

Looking forward to it.  Maybe I'll tackle it after vacation.  Hey it'll
keep Serge from returning it to me @ //SFest with smellybadclutchbake
again at the veryleast right?

-Paul missing, and missing boost K.
