Died, started, no power P1670 & P1211 codes
I have a 2001 Excursion 7.3. It has around 138k on the odo. I have has the O-rings on the HPOP go out while on a long trip (89k on the odo). Had a shop in Wyoming replace the seals/o-rings and haven't had the problem since. Occasionally over the last couple of years it periodically would die when you got off the power and coasted as when approaching a red light. No "service engine soon" light. It would fire right back up and run normally. I have moved around a bit over the years and finally a recall notice hit my mail box for the CPS. I read on here that it would cause the engine to die, so figured I had better take it in. Still haven't. Today rolling down the off ramp after a 40 minute freeway drive (70MPH), it died. Didn't want to start. Finally kicked over but NO POWER and rough, surging idle. No "service engine soon" light. I limped it into the gas station parking lot (2mph max). Figured it was the CPS. Ford was closed. Picked up a NAPA/Belkin unit. Put it in. It fired but the engine was surging still at idle, "Rump rump rump rump" and the engine sounded like it was "nailing" more that usual. The rig is stock stock stock. No modifiers whatsoever. I drained the fuel bowl and replaced the filter (WIX). Let the elec pump run to fill the bowl back up before starting but still more of the same rough idle and no power. I unhooked the battery and depressed the brake pedal a bunch of times trying to reset the PCM (ecu) just in case. Still surges and still no power and won't rev up but now has the service engine soon light on. Bought an OBDII code reader. Throws codes P1670 (electronic feedback signal not detected) and P1211 (electronic control pressure beyond desired). Where do I go from here?
Love the big Rig!
