I don't want to hijack this thread, but while you guys are on the subject and several have posted in the past couple of days. I bought a 99CSVT and the PO had completed a 3.0L upgrade. The fuel system is a return type and the Fuel Pressure Sensor was not installed (it has a regulator, but not one that communicates with the PCM), and the plug that goes into the FPS is just hanging. I am getting a P0193 code indicating a Fuel pressure Sensor, High Input. The car runs fantastic and I hate to add the FPS if it is not necessary. I need to clear the code to pass emissions. Will adding change anything to make it run worse? is there an MIL to trick the PCM into thinking it is getting the right signal?
help me Please.
