really unusual problem

[top_driver]

my car has started to judder when moving along at low speeds like it is out of petrol (not out of petrol by the way) it is ok once reached higher rpm, any ideas what could cause this

I have had this sort of problem after a winter of short journeys, with the car never getting really hot.

Try an oil change and a long run.

Water in the fuel tank ? Probably a long shot but that defeated me for ages a few years back. So thought I'd mention it.

Doe's the engine hesitate on acceleration ?.

faulty injector?

[cazzz1975]

coil pack?

[top_driver]

it just started out of the blue which gets me, i doubt water in the tank, but i don't know

[top_driver]

it always goes on at least a decent journey

1) Worn, faulty or incorrecly gapped spark plugs.
2) Vacuum leak at the throttle body, inlet manifold or associated hoses.
3) Blocked injector / Fuel injection system fault.

Don't go slow, that's my answer!

Fuel filter, air filter ? Either one might need cleaning/ renewing .

[top_driver]

both fuel filter air filter were changed recently, could be the vacuum hose, could be injector, bt i think spark plugs are ok
