Hi All

New member so please be gentle...

I have just purchased my 5th Rover 75, the latest being my 2nd v8, I guess that makes me an enthusiast. However, my 04 75 v8 that I have just purchased runs fine while cold and under normal conditions but following a trip through London yesterday it started to run like a pig in heavy traffic (to the point I nearly fumbled around for my breakdown cover card). The temp gauge did not register abnormal temp and I could hear the fan cutting in and out but undoubtably once I got going again everything seemed better albeit not perfect until I started again this morning from cold. It ticks over warm at around 500 but this varies a lot but from cold it's what I would expect a constant 1k or there abouts.

Not sure what the cause can be, I did think coils but I am no mechanic, it's only done 28k.

Thanks for reading and Help!
