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

Dave

Has the ECU been for a swim in the plenum? Are the drains clear

I would be seeking out an experienced T4 operator in your area. everything else is guesswork.

OP has two threads running on the same subject, pointed him towards Russ in the other one, less than 30 miles away.
