My 92 eclipse runs rich only on hot days or lengthy or if I run it more than about 18 miles on a cool day

Asked by Jun 21, 2012 at 08:07 PM about the 1992 Mitsubishi Eclipse GSX Turbo AWD

Question type: Maintenance & Repair

After my car is fully heated up, it puts out black smoke and runs rich.  After doing research it says that the ECU/ECM could be bad.  When I searched for the part on NAPA website it says that rarely is it the ECU.  It says to check the TCC Selenoid.  Can anyone assist me with this issue?

1 Answer
