Another Quick Question (I Hope!)

2000 1.3 JlX Manual Transmission

Driving along at 30MPH in 3rd Gear and occasionally the car will "judder" for a few seconds and the rev counter goes mad then all back to normal. Tonight it happened twice on a 5 mile journey.

Any ideas??

Cheers
Damo.

wet plugs? just a guess tho.... strange only 1 gear

maybe, i wont have a chance to spend time on it till sunday.
yeah my thoughts, strange it was only one gear ><

sounds like the Speed sensor is freaking out
i would take a look at the connection plug and make sure
its ok.

As it is affecting the rev counter I would look at the cam sensor or crank sensor.

I think you are referring to the speedometer sensor on the transfer box, which would make the speedometer freak out but would not cause the car to judder.

Someone else reported a fault just like this a few months ago and got to the bottom of it with a new sensor of some kind.

Might be worth a trawl through the old posts. I can't remember who it was now unless they announce themselves!

If you can get it put on a diagnostic machine by someone whoknows how to read them cheaply, they might be able to confirm what's causing it.

If they charge too much, some sensors are only £35 a piece and it might be as cheap to start playing trial and error in replacing them if they are charging £100.00 plus for a diagnostic session.

I've got the little box Martin has got that acts as a gauge and trouble code reader and very good it is too - so I can do my own diagnostics. It only cost £100.00 and I have used it already and use the guage part every time I drive it.

I can keep an active eye on the engine temperature for example and although the analogue guage has not risen at full temperature, I have learnt that the engine is running 10 degrees C higher due to mud in the rad, so I can deal with that now before it causes a problem.

If you have the twin cam engine, you might find it a good investment.
