Engine little power on low revs

buchanan · 15th November 2017, 23:01

Today my Rover75 CDTi cut out on me today, the engine was 'chugging' and hand little power as i was reversing the engine then cut out.
I restarted, but once i put the gear box in Drive it cut out again.
When on the motorway it drove fine very smooth. But when i came off the motorway and stopped at lights, the idle was terrible.
Full tank of fuel, new under bonnet pump fitted a year ago, this is an intermittent problem.
One thing we did do was unplug the injectors one at a time, and number 4 made no change to the engine at all.

HAVE FOUND THE PROBLEM TO BE WORSE WHEN ENGINE REACHES NORMAL TEMPERATURE, WHEN COLD IT TICKS OVER NICELY.

Could be any amount of things, and I mean you would be clutching at straws trying to find the cause.

My suggestion would be to have a word with Jonny and Rab at Ards Mini Centre, and get it diagnosed properly, before it lets you down completely.

Injector load drop can be caused by anything from a defective loom to a duff injector, however more commonly a wet ECM causes this

fitted a new UBP it was only a year old, but was running very noisy, could even hear it, through all the sound proofing.
Got in contact with the company i bought it off and they sent me a new one free of charge, seems to have cured the problem.
