Codes 1728,1000,0174,0171,0308,0309,1151,1131,1130,1401, 0355,0340,0122.
I do have the list of what all the codes are. I have cam shaft sensor, clutch slip, DPFE sensor, 4 are lean codes, aditive fuel, Misfires on 1 & 8. Anyhow , Last time I rean the OBDII I got MAF and 7 Misfire. Changed COP and MAF , know I'm getting all these. The truck is a 1999 F-350 Super duty 5.4ltr gas. Automatic. It only has 58,000+ , Anyhow today I'm tackling the cam sensor and Diff Pressure Snr . Connected the Cam Sensor to the AC on the multimeter and ran a piece of metal infront of it , got no pulse , but got a pulse on DC.....?Why do I get one on DC and not AC? Anyone have a small caliber pistol for sale , that should take care of all this trucks problems...............

 

Also , Its problem is it runs rough for a little while the (on Highway) you start to loose the throttle/accel and slow down to 35-40 on a slight incline. If you put it in nuetrel and shut it down while coasting (to reset the computer) it goes away a little but comes back in a few moments.(Enough to get over the hill) Uugh!!!!

 

Cam shaft sensor to no avail , Still issues . Today I tackle the O2 sensors and the other 7 COP sensors. I will also check the EGR and check the injectors. Anybody , please reply with any suggestions , could really use a hand with this one.

 

Did all of these codes pop up all at once or over a period of time? Because if they came up all at once, I'd find it hard to believe that all these sensors will go bad at once. Is it possible its an elecrtical problem, like a faulty battery or a malfunctioning computer? Just throwing some ideas your way.

 

Is there a chip or aftermarket programer installed? Like michael said I find it hard to believe that all those would go bad at the same time. I wouldn't put it past a bad computer. I'm not sure how many MAF's are available but are you sure you got the right one for your truck. That will probably mess alot of stuff up with all other sensors possibly. Maybe put your old MAF back in if you still have it and see what comes up. Keep us informed.

 

Okay ,the way to approach this is write down all your codes .
Then clear them via the scanner start the truck and monitor the scanner
take the first code that pops up and work on that one first.Then move down the list of codes after clearing the first one.then start the truck and monitor it
This is the only way that you can get out of this mess,short of using the pistol !!!!!!!

I hope you haveyour own scanner though could be a real pita if not

Have just finished replacing O2's and COP system , I checked the egr ---with vaccuum the motor dies down and stalls. checked the DPFE for clogs its free and clear. Already changed the cam sensor. Also what does the codes p-0355 (IGN Coil E Pri/Sec CKT Fault) and P-1130 (HO2511 Adaptive Fuel at Limit) Point too?
Thanks for the responses

 

Got this code on OBDII , Said "no description" . Got all the codes down to 0174 (To lean bank 2) and 0171 (To lean bank 1).replaced both the O2 sensors on the

 

Possibly PVC or that plastic intake. What the heck is going on at ford? PLASTIC ON ALUMINUM. Doesn't take a rocket scienctist to figure out that equation. Anyhoo , Really a son of a @$%#@ to get to the pvc hose at the back of the motor. What other possiblities can come from both banks having a reading. It's got to be an all over issue correct?

 

Anyone know if 5.4's have the 90 degree elbow at the front of the intake that goes over to the PCV on the passenger side valve cover like the v-10's have? I know that it's common that they crack sometimes causing lean codes. Not sure if they have them in the front of the intake on the 5.4's.
