i think i am having fuel injector problems on my 02 Discovery,
At first i thought it was the pcv valve, "when at an idel it sounds like it is starving and spudders ever so often, then after a while the service light came on, a day later it went off.
i went to get a pcv valve at O' rellys and they said the dealer has not released that part yet.
"Accually my wife went to get the part and that is what they told her, I was working out of town. anyway, i need to get that part, any suggestions, and i would like to put a injection cleaner in the fuel, any suggestion, i heard "sea foam" was good stuff
any input would be great
thanks

 

lucas oil.....injector cleaner is the best I have found. I gained almost 2 mpg after the second tank full with it added. YMMV.....[sm=icon_guiness.gif]

 

What about a pcv valve, O'relleys and autozone does not carry this
autozone told me it is not needed, whats up
thanks

 

I'm not sure that you've got problems with the fuel injectors. Discovery with Td5 engine has these problems and the only explanation is CABLES. I think you have to change the injectors cables. These cables are in the engine. Just remove the cover of the enjine and you'll see these cables, buy another one complect cables, clean the cables connector with WD-40. Then remove Engine ECU /it is in the area behind right main lamp/ check the ECU's connectors /probably there is oil from the engine/ clean them and your engine will be all right.
wish you luck!

 

i replaced all the spark plugs to day and the problem seem to go away
it seem to have a very little sputter only on idel. the guy at autozone pluged in the little computer and it said plug 1 and 6 missfire
or fuel filter or fuel injector or vacum leak
in that order
so i replaced the pluges and bought a new fuel filter.
I cand find were the fuel filter is located autozone sold me what looks like a generic one off the shelf . i dont even know if it is right.
i thought it would be located behind the R/R tire but i cand find anything that looks like theis
please HELP

 

you should be able to see it to the uper front of the passenger rear tire. stand looking at the pass/rear tire then look above it to the right.

 

After a lot of trouble shooting and $300.00 later
the problem was not the fuel injectors
it was the sprank plug wires 1&6b to be exact.
o well at that was the cheaper route.
thanks for the help
i guess you Live and Learn that way.
