stevenM Posted July 23, 2005 Report Share Posted July 23, 2005 I have a 1993 Eldorado Sport 4.6L. The car is having problems with fuel load up. I have replaced the following. Map Sensor O2 Sensor Fuel Pressure Regulator TP Sensor TP Switch Ignition Module Spark Plugs Checked and Cleaned Injectors Checked Injector Drivers- It Seems They Are Open All The Time... I Have Tried Using Three Different PCM's I start the car and it belches out black smoke. It clears when at high RPM, and loads up at lower RPM. It sucks up gas so fast I can't beleive it! Is it possible the injectors are staying open all the time, and if so would it do it with three different PCM's? Stumped in Denver Link to comment Share on other sites More sharing options...
