strange jerking

[mattsbrad]

hey i have an X - reg LX 206
all has been fine apart from the windscreen washer breaking and the exhaust rusting off bout otherwise all was good untill yesterdya
in teh morning it was fine
but then in teh afternoon i got in and something was weird
when every the engin revved higher than about 2500 therew was a weird jerking movment and tehre was no acceleration whatsoever
it was like a knocking but more like i was trying to acclerate too much in first gear and it was jerking there was also a weird jerking noise coming form the engine
does anyone have any ideas

Did engine management light come on? Did you put fuel in it or wash it?

[mattsbrad]

the engin light is on b ut then it always seems to be on
since then i put fuel in it and well some times the jerking happens sometimes it doesnt it just is like i cannot drive in any gear under fourth without teh whole car rolling around

hmm this is a long shot you could have a clogged up fuel filter. i get that jerkin notion with the car twice recently and i suspect its due to the very low amount of fuel i been running....

Have you started using supermarket fuel?
