Rover 75 1.8T Jerky ride
Hi, can anyone explain to me why when I turn the ignition switch to the second
position and push the excellerator down 5 times the temporary jerky running stops and the tickover resets if it was running faster than normal at the time. The increase in tickover speed seems to coinside with jerky running I think. I have tried several times to correct the jerky running by changing fuel filter and plugs etc which sometimes temporaly corrects the fault but returns to jerky running later. Regards Ken |

Get a diagnostic check done on it; check the wiring to the coils and plugs, and maybe, try a temporary swap with a coil and run it.
Good luck. |

Hello Ken,
Those with experience of it advise against touching the filter as it's apparently very difficult to reassemble the canister without distorting the seal. Maybe that's what's happened with your car Ken as the fuel pressure would be affected. Does your filter canister have the orange/white clip fitted? Simon

At the risk of dragging this off-topic, I believe it's perfectly reasonable to change the fuel filter. Like most things fuel-related in the 75, it is a bit fiddly to reassemble but far from difficult if you take your time and are careful. It's the exact same design as the Mini Coopers of similar age, and for them is a service item - mini forums have plenty of members sucessfully changing filters without issue. I predict over the next few year we'll start to see more and more of our cars with fuel pressure problems, as the pumps progressively weaken or the filters become clogged. |

Try to evaluate the options and take easier and cheaper steps first.
