[s-cars] Intermittent cutout resolved - maybe

[Robert Myers]

Hi Y'all,

A week or two ago I posted about an engine cutout problem.  I got 
several helpful replies and I've spent several enjoyable days under 
the hood, under the dash, and inside the trunk searching out and 
eliminating possible problem sources.

Finally, this morning, I eliminated the last suggestion (faulty 
engine speed sensor - that wasn't it).  Thinking...  "OK, what's 
left?  It's just as if the ignition switch is being turned 
off.  Hmmm...  I wonder...  I think I have a new ignition switch in a 
box somewhere.  Search-search-search-aha!  Here it is."   Pull the 
instrument cluster, pull the old switch and stick the new one 
in.  Crank the starter and the engine fired right up.  OK, that's 
good so far but it would start earlier and then die in a few 
minutes.  Let it idle.  It idled for ~15 minutes - slightly rough 
like maybe the ISV could use a bit of cleaning.  OK, climb in and go 
for a short drive.  Engine ran fine.  Come home and let it 
idle.  After an hour it's time for another short run.  Did 
fine.  Came home again and shut Ms. Piggy down.  I'm starting to feel 
encouraged.

The funny thing is there were no other symptoms of a bad ignition 
switch.  The HVAC system ran.  The lights worked.  The windows 
worked.  Etc.  Everything was working normally - except the 
engine.  However, it's beginning to look like the engine cutout 
problem _may_ be resolved.

Now the next job.  Solve the low boost problem.  Maybe already 
resolved, however, disconnecting the downpipe from the rest of the 
OEM exhaust system gave an immediate increase in max boost from ~18 
psig to 23-24 psig.  The new Stromung downpipe and rear muffler 
sections (on order and, I hope, on the way here) along with my 
existing "test pipe" should help a lot to cure a plugged kitty.  ;-)
