Diagnosing Quad 4 ECU problem

[Neville Newman]

i don't remember how to dump the codes, but i can tell you this.
The best way to diagnose these problems is to find a shop (likely
not a dealer, unless it's also a Hyundai or Mitsubishi dealer) 
that has a Simu-Tech machine.  Snap-On/Sun now sells them, so check
at known Sun shops.  It will hook directly up to your ECU (not the 
ALDL port) and do full static and dynamic diagnostic checks of all
the sensors, actuators, ECU, grounds, etc.
