Hi All

I have a really frustrating and very dangerous problem with my Micra. I bought it privately a couple of months ago in really good nick with 50k on the clock, and it ran ok for a few weeks but recently it has been a swine to drive as it is struggling to do anything over 40-50mph. Car is a 2003, 1240cc petrol, 2door.

I will try and explain the problem but if you need any more info please get in touch. It will drive fine up to about 40mph but anything over say 4th gear and the car judders and just feels like the power is going to fail, it doesn't totally fail though, it will continue at about 40-50mph maximum (juddering), if I touch the accelerator slightly it seems to maintain its current speed and there seems to be power there ok until I press it down harder there is nothing there at all. It will run forever idle, in fact it sounds like it is running lovely at a stand still.

I'm really worried because I need to drive approx 10 miles down the motorway two evenings a week but in the last few weeks I have had some really nail biting journeys as my Micra seems to lose all power when I get over approx 40 to 50mph, obviously this means I need to pull over on a really busy motorway in the dark, one particular trip I had to stop 5 times and I was shaking by the time I reached my destination. After that really bad trip I took it into a garage who ran diagnostics which turned up nothing, they checked everything they thought may be the cause but one thing they couldn't get to was the fuel filter as the guy said it was hard to get to. He also gave the car a winter service and when I got it back it ran ok (but only ok) for a week or so but the problem is back and I'm gutted.

The car actually passed its MOT last week as well, needing only a headlight bulb, so that didn't flag up any problems so I am totally at a loss, I seriously darent drive it on the motorway until it's fixed and this is a big problem to me. Has anyone had a similar problem with a Micra? Any help would be awesome as having a car is essential right now.

One other thing I have tried is turning the ignition on and off whilst driving down my road, I was told this may re-set the engine management or something but it hasn't solved problem. I am totally skint right now so I really can't afford to keep paying to get it looked at but it not getting fixed.

Any help or advice with the problem would be really really appreciated as I need to try and solve this problem urgently. Many thanks in advance for any advice you can offer. Read more

I was wondering if anyone knows what happened to Proton in the UK. My great aunt has had the same proton since 1991, and would now like a car with power steering, however I can't seem to find any new protons, but also no evidence that they no longer sell cars in the UK.

Have they slunk quietly away? Read more

So I was driving and had been sat at these lights for 10 minutes without it changing, it was late and there were no cars around so I went through. Bad of me I know but I was honestly there for 10 minutes before making this call. Does anyone know if the round black thing on top of the traffic light is a sensor or a camera? Im worried it's a camera and that I should be expecting a penalty and points. Any help would be great thanks! Read more

Hey, I'm new to the forum. Does anyone have any advice on when the Cambelt should be changed? I seem to get conflicting information that frankly confuses me. My car is about 9,000 miles shy of reaching 100,000 miles. No Cambelt change noted in the service history. Read more
