Rover 75 rough idle and juddring when driving
 

HELP I am out of ideas!!!!!


I have a Rover 75 2.0cdti its a 2003 auto model. The tick over is erratic, and when I am driving along its like got a judder, like a slight misfire?? I have changed the MAF, the fuel rail sensor, the fuel filter, the under bonnet fuel pump Checked the fuel pressure out of the under bonnet pump thats fine, there is no air from the tank to the pump. I replaced the injectors, the injector wiring harness all to no avail. On the snap on diagnostic there is no faults stored except a heater plug code which wont cause the isssue thats driving me NAUGHTY WORD-NAUGHTY WORD-NAUGHTY WORD-NAUGHTY WORD-NAUGHTY WORD-NAUGHTY WORD- insane.. I live in Rossendale Lancashire would really love some help.


Cheers

:} I'm no Diesel expert

Is there a reason why you would discount a Glowplug fault :shrug: surely this would cause the symptoms you describe ?

judder
 

I have always had a glow plug fault code for the six years I have owned the car and its been fine, most of the time the ECG valve has been disconnected etc so thats why I discount the glow plug as a cause, so many sensors doing so many things lol.

BigRuss, one of the knowledgeable experts here is less than 30 miles away from you in Liversedge. Have a word with him.

cheers will do

Not on a diesel it won't, 99% of the cars I see have the self same fault and are all running perfectly.

I'm more surprised if I don't see it ;)

Russ

:duh: Correct me if i'm wrong....lol...... Surely a GlowPlug that is not functioning as intended Could cause misfire symptoms as described ? :shrug:


regardless of the "Fault Code" ;)


Paul.

Not at all Paul ;)

None of my cars have functioning glow plug relays, and I find most diesels are the same.

It is a pleasant surprise when you find one that actually works, they are few and far between I can assure you.

Brian :D

M47R engine...Glow plug relay waste of time unless you want to go somewhere mega cold :D

Just a line to say I went over and seen BIG RUSS he was very helpful, plugged in his T4, fitted a ecu to try that did all sorts of stuff, but like me he is stumped LOL. suggested change eng wiring harness as it may have a bad connection or a break in it, so thats something for me to try. But a big thanks to Russ for all his hard work.
