Can you give us more information? Year, Model, Engine type, etc?



Sorry:)

It's a 1995 Ford Contour with the 2.5L It has 91,000 Miles(146,000 Kilometers).

I'm racking my brain right now searching ALL over the web trying to find similar symptoms and solutions...but am pretty much drawing blanks:(

I pretty much think it HAS to be wiring or PCM related...how else can disconnecting the IAC, TPS, MAF, and pumping Open the EGR valve NOT produce a corresponding DTC???

I know there's that EEC Relay thing, but I don't think that could be it...because when I do the KOEO Self-Test, I still get the stupid DPFE Sensor voltage below minimum test value of 0.2 volts, but KNOW that this is not the actual cause of the problem..plus the DPFE code is just a Memory code...the Check Engine light is not on at all when the engine is running(only by reving the engine).

THANKS AGAIN!
