Hi
My 2009 E350 5.4L starts up very nicely and in idle putting in gear she will move but if I accelerate she quits. I was told is catalytic convertor problem but the convertor looks new replaced, one may think it maybe the sensors so I got two upstream and replace them but now she wont stay on but two seconds. I did not replaced the downstream (one only)
Are the old sensors cleanable? or what mite be the right part in case the one I got was not the right ones. So what you guys think it may be the problem
Thanks

 

Something is not right here.

You are telling us your vehicle is a 2004 - E350 and showing us a sticker for a different vehicle.

A plugged catalytic converter will produce the symptoms you describe..
The problem is with the cylinders on the passenger side of the engine.

You should consider getting the correct oxygen sensors in there and replace that converter. If you give the parts store the wrong info , you will get the wrong parts.

 

You right I have the wrong year I changed the year for future participance
What you mean by this (The problem is with the cylinders on the passenger side of the engine.)
So you say the sensors are not the problem?
The converter was replaced recently do they go bad this soon?

 

What do you me by that "The problem is with the cylinders on the passenger side of the engine" can you explain please

 

Bank 1 is the cyl bank on the passenger side of the engine.
The code is telling you the converter is not doing it's job of cleaning up a pollution problem.

The converter has reached it's limit on what it can clean up.
The oxygen sensor tells the computer too much fuel or not enough air is getting into the cyls on bank1.
Called running rich, and if running rich long enough it will destroy the converter. Maybe somebody replaced the converter and that is why it looks new, BUT,,,,,,,,,,,,,,,,,,
they did not fix the problem that destroyed the original converter.
Now,,,,,,,,you still have a running rich problem AND another bad converter.
Converters are not cheap and if the REAL problem with bank1 is not found and corrected, it will keep destroying converters.
What you might consider is to have a good shop with a capable scan tool pin down the exact problem..

 

I understand that if you don't fix/cure the source of the problem parts will keep breaking But,,,,,,,,,, if you change the infected parts you expect to see some improvement, until the parts get destroyed again will you agree?
Therefore I replaced the oxygen sensors' and the converter toway and yet no improvement whatsoever. So if their no more thinks to check and replace, getting a mechanic with a scan tool their no sence keep spending money on a fishing expedition will you agee?
Thank you hunky for your inputs

 

I went by the info you posted from your code reader. Evidently the vehicle has more than one problem..
When was the last time the fuel filter was changed ?

 

Filter is new the fuel pressure is 50/15

 

Please take a look under the back of your vehicle and see if you have a fuel pump driver module mounted on the chassis cross member.There should be one there.

They were known for corroding where contacting the cross member and that corrosion caused all kinds of problems.
Let us know if you see anything there, thanks

 

I checked the fuel pressure the pump is on the side of the trany and it pressurize the line at 50 lb when I turn the key then it lows to 15 lb is that what suppose to do?
