Mitsubishi Repair: EGR Code on Computer, Car runs rich and idles rough, intake hoses, eclispe


Question
1994 Mitsubishi Eclispe, 2.0L, GS, Manual.  Great Car but I can't figure out why it idles rough and the computer gives a EGR Code.  I've cleaned the EGR Valve and replaced the EGR Vacumn Selinoid.  I also had the Cat's checked to see if they were bad, and they weren't.  When I replaced the Selinoid I reset the computer and so far the Ck Engine light has not come on again.  Car still smokes as though it's running rich.  Your help is appreciated.  THANKS

Answer
Wallace,
You may want to clean out your throttle body and intake manifold.  Sometimes a dirty intake can cause false reading on your ECU; especially for your EGR valve.  If you continue to run rich, you may want to think about having your O2 sensor replaced.  But before you send any money on that, check all your intake hoses and senors.  You may just need to do some more cleaning.
Good luck!
