Steps I took.
Hooked up ALDL to ElanScan USB (Windows 7), Ignition turned on.
1) Start Talking --> Getting "No Reply" continuously -- checked latency setting and it was set to 1, not sure how to get this to work.
2) I went to SETUP in ElanScan and selected "Test Mode". This time when I pressed Start Talking, it worked!
What is Test Mode and how is it different?
3) Start Logging (still in Test Mode) and took it for a drive around the neighborhood. Unfortunately, couldn't really open it up too much, a lot of stop and go traffic and didn't want to risk getting in a major road and risking engine failure.
4) Saved log (attached).
Background on the car/repairs below, but bottom line right now is I have CEL 41/42 and definitely not running 100%, very inconsistent (runs well for a little bit, but stalls out every once in a while, exhaust pops every once in awhile, etc.) From what I have read, it sounds like it could be any of the following:
Ignition Control module
HES (even though it was replaced 1k miles ago)
Gaps on HES sensors
Timing
Entire CAS (which would also include the magnetic pickup)
Sparkplugs
Leads
Coil Packs
HT lead on coil pack
Earthing on coil pack
ECM
Any advice on next steps?
BACKGROUND
91 Fed, about 40k miles on it now
July 2010 (when it had about 37k miles),
Experienced some mis-firing (no CEL)
-Replaced Ignition Wires
-Coil Packs
-Spark Plugs
-Yokohama S.drives on all 4's
Things OK until...
August 2010, experienced some overheating while driving (fans did not engage)
-Replaced Thermostat (the existing one was definitely stuck according to boiling water test)
Things OK until...
November 2011
Experienced mis-firing again (no CEL) - this time very badly, sounded like a helicopter driving and not all cylinders firing
Also noticed some loose metal chunks in my muffler (disintegrated cat?)
-Purchased Head Gasket Leak Kit -- no signs of HGF
Car basically sat in garage until...
March 2012
Running ok (mis-firing magically gone), but then get CEL Code 41
Garaged until...
December 2012
Car towed to mechanic for a flurry of repairs and upgrades:
-HES replaced
-New timing belt
-Piper stainless 2.25" w/sports cat
-Piper ceramic downpipe
-Wastegate ported to 20mm
-02 sensor
-Oil Cooler replaced/Oil Pan Gasket/Valve Cover Gasket
-ProTech suspension (w/SJS springs)
-Front upper ball joints/Front lower ball joints/Front lower control arms/Various bushings
-Rotors/Brakepads/Stainless hoses/Master Cylinder/Caliper Seal & Sliding Kit
Car runs like a champ, except boost creep when pushed extremely hard until...
July 2013
Less than 1k since the above work, CEL Code 41 and 42 (can HES go bad that quickly!?) and car very jumpy
Garaged for almost a year (frustrated with dumping money in the car) until...
September 2014
Mechanic doesn't really worry about CAS/HES or EST (Code 42)
-Fuel filter replaced
-Thermostat replaced
-Temp Sensor replaced
Car runs much better than it did when I drove it to the mechanic (very jumpy, stalling out), but still have CEL 41/42 and definitely not running 100%, very inconsistent (runs well for a little bit, but stalls out every once in a while, exhaust pops every once in awhile, etc.)
