my rover 75 diesel lacks power???

yorkie72 · 25th October 2009, 17:54

i have drove for 200+ miles today and my car drove great but then when i come back into my town,i pull away from a jun in first and it then has a lack of power and it does it in every gear??/

i have changed my fuel filter and air filter before i went on todays jounery and it was great,so i do not think its most but does anybody have a idea????

Does the radiator fan work? I had this, admittedly on a rather hot day, but the diesel overheated, and went into what I can only describe as "limp home" mode, wouldn't rev above 2000-odd rpm, until I got out of traffic and the rad had some airflow through it.

Replaced the fan motor, and no problem since.

i will check it tom,thxs

Common things to check/do I suppose are:

Intercooler seals (affects torque under 1500rpm)
MAF sensor (affects performance under 2000rpm)
Clean EGR valve (could give hesitation at certain points in the rev range)

it seems to rev ok until it gets to about just over 2000 revs???

how easy is it to take the egr value and clearn it???/

I had the same prob and changed the MAF and its now a compleaty diff.

Don't laugh but can I suggest you check the mat in the drivers foot well, mine slides under the pedals and makes a big difference to the performance.

Seems to point to airflow, the turbo kicks in at 2000RPM and it does not seem to be doing it's duty

Intercooler rings.

Hi. I had hesitation at 3000rpm so I replaced the maf last wednesday, you would not believe the diff. The egr is easy to remove but cleaning is very messy, but it does improve air flow a little but the ideal is a bypass valve. I am waiting for one at the moment.
