1998 Rover 4 Series

Hi there,

Thank you for the donation,

We do not have any information on your car in our data base, so I will out line the basics as this is where you should be starting anyway, first thing is to go get a scan and check for any unresolved fault codes, not all fault codes will set the engine check light, get a full tune done, and have the fuel rail pressure check, also fuel pressure retention. As for the noise I would be looking at cracked exhaust heat shields, broken exhaust mounts and loose exhaust muffler baffles, start here.
