wow...what did you do to that poor thing? I might be wrong, but allot of those seem unrelated.

Hopefully a tech chimes in, sounds expensive though

Is this a HARD fault or one retrieved in memory? Does this engine misfire? If not, I'm guessing that it flagged cylinder number 3 low during cold engine start up. Otherwise you MAY have number 3 injector going south.

Do you have any turbo issues? If not, either the EGR valve is not shutting fast enough or your truck needs a reflash to the latest calibration to prevent a false setting of P0404

Is it chipped? Have you been playing around with the settings?

Disconnect your glow plug connector on each buss bar (the one with the coloured wires) Get your DVOM (set to OHMS) out and connect the black lead of the meter to the battery negative post, and the red lead of the meter to terminal on the connector end that goes to each glow plug. You should be getting readings of 0.5 to 2.0 OHMS on each circuit. If this checks out good, either you have a wiring issue between the GPCM and the glow plug buss bar, or the GPCM itself is faulty

Does this have an aftermarket intake? A lot of times aftermarket intakes will set this code, if you have one of those air filters that you "clean" and re-oil. If this oil gets onto the MAF, it will bugger up the MAF input to the PCM. Either that or there is a problem with the MAF circuit. Did you leave it disconnected by mistake?

im not sure if its a hard fault or memory? what is the difference & how do i tell? no missfiring so why would #3 be low durring cold start up, is that something i need to worrie about?

no turbo issues im assuming i can just tale it to ford & have them do a recalibration? i just cleaned the egr valve if its not shutting fast enough time for a new valve?

it was chipped but not any more so clearing the codes should take care of this right?


Disconnect your glow plug connector on each buss bar (the one with the coloured wires) Get your DVOM (set to OHMS) out and connect the black lead of the meter to the battery negative post, and the red lead of the meter to terminal on the connector end that goes to each glow plug.

i'll check the ohms tomorrow
